Best ResponseYou've already chosen the best response.0I tried to get the answer by doing \[12.5 \times 3.5 but \it turned out \to be 43.75 which was \not there. ;; sadly\]

Best ResponseYou've already chosen the best response.1You just need to find area of big circle and small circle using \(A = \pi r^2\) THEN you subtract big circle by small circle.

Best ResponseYou've already chosen the best response.1First convert diameter into radius

Best ResponseYou've already chosen the best response.0how do i do that?

Best ResponseYou've already chosen the best response.1Let's just find area of bigger circle. diameter is 12.5 So what is radius?

Best ResponseYou've already chosen the best response.0:/ radius is....a line segment that joins the center of a circle with any point on its circumference. (yes i looked it up)

Best ResponseYou've already chosen the best response.1no no I mean what is length of radius in bigger circle?

Best ResponseYou've already chosen the best response.1Radius is 1/2 the diameter, right?

geerky42

Best ResponseYou've already chosen the best response.1So to find radius, you just divide diameter by 2

geerky42

Best ResponseYou've already chosen the best response.1Yeah, so now find area: \(A = \pi(6.25)^2\)

Best ResponseYou've already chosen the best response.039.25 i got kind confused on this part

Best ResponseYou've already chosen the best response.1What are you confused with?

gabbyalicorn

Best ResponseYou've already chosen the best response.0just that whole part with the a= π(6.25.....etc thing

geerky42

Best ResponseYou've already chosen the best response.1\(\pi\) is pi. You can use 3.14 for that. \(etc~^2\) mean you multiply "etc" by itself For example \(4^2 = 4\times4\)

Best ResponseYou've already chosen the best response.1Does that make sense?

geerky42
 one year ago
Best ResponseYou've already chosen the best response.1OK so \(A = \pi(6.25)^2\) First, multiply 6.25 by itself

geerky42

Best ResponseYou've already chosen the best response.1Then multiply it by 3.14

Best ResponseYou've already chosen the best response.1Good enough. This is area of bigger circle. Keep that in mind. Now do it again, but with smaller circle (with diameter 3.5). Can you find area of smaller circle?

gabbyalicorn

Best ResponseYou've already chosen the best response.0so replace 6.25 with 3.5

Best ResponseYou've already chosen the best response.1oops forgot to convert diameter into radius

Best ResponseYou've already chosen the best response.13.5 is diameter, so what is radius?

geerky42
 one year ago
Best ResponseYou've already chosen the best response.1No. To get radius, you divide diameter by 2.

Best ResponseYou've already chosen the best response.0I dont see it as the answer ;; i think I did something wrong

Best ResponseYou've already chosen the best response.0oh wow the online calculator was way off

geerky42

Best ResponseYou've already chosen the best response.1Yeah. so radius is 1.75. Now find area of circle.

Best ResponseYou've already chosen the best response.01.75 x ? = ( 12.5 ) ?

geerky42

Best ResponseYou've already chosen the best response.1No. \(A = \pi(1.75)^2\)

Best ResponseYou've already chosen the best response.0no, that is the diameter

anonymous

Best ResponseYou've already chosen the best response.0yep, now find the area of the smaller circle

gabbyalicorn

Best ResponseYou've already chosen the best response.0okay, so the smaller circle is 3.5

Best ResponseYou've already chosen the best response.03.5 is the diameter, what is the radius?

anonymous

Best ResponseYou've already chosen the best response.0no its half the diameter

anonymous

Best ResponseYou've already chosen the best response.0no what is the diameter of the smaller circle?

anonymous

Best ResponseYou've already chosen the best response.0yes, and the radius is half of that

anonymous
