A cylinder has a diameter labeled twelve inches and height labeled fifteen inches.
What is the area of the horizontal cross section of the cylinder? Use 3.14 for π.

Answer 1

• 113.04 square inches

Explanation:

Horizontal cross-section of a cylinder is a circle with same dimension as its base

Given diameter

• 12 inches

Area formula

• A = πr² = πd²/4

So the area of cross section is:

• A = 3.14*12²/4 = 113.04 square inches
