For Part A Area of a square = \(\sf \pi \times r^2\) Where, r = radius = diameter/2
Can u do it now?
umm i still dont get it :(
for part A, a?
are you sure?
Yes, are you?
now lets do part b
No wait, no it's wrong.
One silly mistake.
what is it
Diameter is given 8, so radius will be 8/2 = 4. Correct?
Now, putting this value of radius in the formula I just told you we get area = \(\sf \pi \times 4^2\) = ?
whats the symbol in the beginning mean?
It's called as "pi" and its value = 3.14. So if it is written \(\sf 16 \pi\), it actually means 16 \(\sf \times ~\pi\) or if you want to simplify it more it means 3.14 \(\sf \times\) 16
Moving on to the question, the correct answer for part A is?
i got 16
Yes, \(\sf 16 \pi\) square inch to be more precise. Don't forget the "pi" !
ok thank you so much... dont leave because i will be tagging you again!! :)
I m not leaving, so shall we move to part B?
So, any idea about Part B?
whats the equation, ill solve it
This is ur square frame which is 2 inch wide. Area of a square = \(\sf side^2\)
So the answer should be?
we did the part B wrong..
whats the equation
The frame is also circular and surrounds the circular picture. It says that the frame is 2 inches wide. Thus the radius of frame would be 4+2= 6 inch.
Now, find the area by same equation u used before.
i got 36
Are you missing something? Only 36?
and 36 pie
Correct 36\(\sf \pi\) square inch. Don't miss the pi if u want a apple pie (-:
It's Pi not pie. Pie is the one u eat.
lol thanks :)
