D is the answer.
LA of cube is 4(2r.2r) = 16 r^2
LA of cylinder is 2πr x 2r = 4πr^2
16 r^2 - 4πr^2 = 4r^2(4-π)
I think the answer would be = 16/5 = 31/5 and the other part to the simplest form would be 625/10000<span> = </span>1/16<span> when reduced to the simplest form........</span>
The answer would be C. Hope the picture helps.
28.26 feet squared
Work:
A = π r²
A = 3.14 (3²)
A = 3.14 (9)
A = 28.26
