Find the surface area of a cylinder with a radius of 5 inches and a height of 10 inches. Use the approximation 3.14 for pi

3 answers

Surface area = 2πr2 + 2πrh

Surface area = 2(3.14)(5^2) + 2(3.14)(5)(10)

Surface area = 314 + 314(10)

Surface area = 314 + 3140

Surface area = 3454 inches^2
nope, canned answer is wrong again

Surface area = 2(3.14)(5^2) + 2(3.14)(5)(10) <--- it had that right
= 157 + 314
= 471 in^2
