Answer 1

Answer: 2465 and 1011650

Step-by-step explanation:

A cylinder is like a circular prism so its base is a circle and the formula for the circumference is 2πr

2r = 176/π

r = 88/π

Its surface area has a formula of πr^2

Surface Area = π (88/π)^2 = (88^2)/π ≈ 2465 cm^2

Surface Area of cylinder = 2πrh + 2πr^2 = 2 x 88 x 88 x 65 + 2 x 2465 = 1011650
