Answer:

The radius is r = 3 in,
The height is h = 4 in

<u>The area of the base:</u>

A(b) = πr² = π(3²) = 9π in²

<u>The circumference of the base:</u>

C = 2πr = 2π(3) = 6π in

<u>The area of the lateral surface:</u>

A(l) = Ch = 6π(4) = 24π in²

<u>The surface area:</u>

S = 2A(b) + A(l) = 2*9π + 24π = 42π in²
