Best ResponseYou've already chosen the best response.2Diameter is given 8, so radius will be 8/2 = 4. Correct?

Best ResponseYou've already chosen the best response.2Now, putting this value of radius in the formula I just told you we get area = \(\sf \pi \times 4^2\) = ?

Best ResponseYou've already chosen the best response.2It'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

Best ResponseYou've already chosen the best response.2The 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.
