how to find the radius and circumfernce in a circle

This Question is Open

Best ResponseYou've already chosen the best response.2formula to find circumference \[\huge\rm C= 2 \pi r\] r =radius if the given is diameter then you use \[C= \pi d \] remember radius is half of diameter \[\large\rm r=\frac{ d }{ 2 }\]

Best ResponseYou've already chosen the best response.0ive seen a problem where it just gives a circle and says find the radius.. how is that possible if it doesn't give anymore info on it?

Best ResponseYou've already chosen the best response.0how did you find the radius if it doesn't give any info on the circle

Best ResponseYou've already chosen the best response.0ok actually here is another problem i have str8 from the review

Best ResponseYou've already chosen the best response.2radius is half of diameter and diameter is straight line passing through the center of the circle

Best ResponseYou've already chosen the best response.0dw:1443384671583:dw find the circ and area of each circle. round to nearest 10th

Best ResponseYou've already chosen the best response.2yes that's the diameter a line passing through the center now use the formula to find radius i repeat radius is `Half` of diameter \[\huge\rm r=\frac{ d }{ 2}\]

Best ResponseYou've already chosen the best response.2r=radius d=diameter so you can replace d with 8

Best ResponseYou've already chosen the best response.0its not asking for the radius its asking for the circumference and area though

Best ResponseYou've already chosen the best response.0sry 2 instead of 9 at the front

Best ResponseYou've already chosen the best response.2yes right ! \[\large\rm 2 \pi 9\]

Best ResponseYou've already chosen the best response.0mind if i give 1 more example?

Best ResponseYou've already chosen the best response.0oh and how do i find the area? thats also what it asks

Nnesha

Best ResponseYou've already chosen the best response.2oh to find area \[\huge\rm A= \pi r^2\]

Nnesha

Best ResponseYou've already chosen the best response.2yes right you can use pi but if it says write answer in terms of pi then 81pi is the answer

Best ResponseYou've already chosen the best response.0dw:1443385350101:dw find circumference and area

anonymous

Best ResponseYou've already chosen the best response.0so circumference is 26

Nnesha

Best ResponseYou've already chosen the best response.2remember it's \[\huge\rm C=2 \color{reD}{\pi} r \]

anonymous

Best ResponseYou've already chosen the best response.0meant diameter is 26

Nnesha

Best ResponseYou've already chosen the best response.2yes right diameter is 26 :=)
