Acircular picture is 8 inches in diameter.

part a.
what is the area of the picture in square inches.
a. 4 square inches
b. 8 square inches
c. 16 square inches
d. 32 square inches

part b.
a frame that is 2 inches wide surrounds the picture. what is the total area of the picture and the frame in square inches?
a. 4 square inches
b. 12 square inches
c. 36 square inches
d. 40 square inches

part a: 16 sq in./ part b: 36 sq in

Step-by-step explanation:

part a: area= π*r² = π(d/2)² = π*(8/2)² =

π*4² = π*16 square inches

part b: d=8+4 = 12     r = d/2 = 6 in

Area = π*6²

=36π

your answer   is c

step-by-step explanation:

6^2 or 36

step-by-step explanation:

6000n

6×1000n

6×10^3 n

so we need 6n need to be a perfect cube

so n has to be 6^2 so that 6n is 6^3

what i'm saying is if you let n be 6^2 you have 6^3×10^3 or 60^3 which is a perfect cube
