# What is the surface area of a cylinder with a radius of 7cm and a height of 25cm?

The formula in getting the surface area of a cylinder is 2 pi r 2 + 2 pi r h SAC = (2)(3.14)(7) 2 + (2)(3.14)(7)(25) = (2)(3.14)(49) + (2)(3.14)(7)(25) = (6.28)(49) + (6.28)(175) = 307.72 + 1099 SAC = 1406.72 cm 3

# What is the area of a nonagon with the side of 4cm?

The area of a nonagon with side L is 6.18182 x L squared. If L = 4, L squared = 16, so area is 98.91 square cm. Now I didn't know the formula, I got it from Wikipedia, so you could do that too.

# 2 regular pentagons have radii of 5cm and 7cm What is the ratio of their areas?

Given the radius R (distance from the center to a vertex), the area of a regular pentagon is given by: . R 2 5sin(2pi/5) ---------------- 2 . So, since the rest of the formula is a constant, to determine the ratio, you just need the ratio of: . 5 2 : 7 2 = 25 : 49, or 1 : 1.96 , or ( Full Answer )
