Question

A cylinder has a radius of 10 inches and a height of 6 inches. About what is its volume in cubic inches? Use 3.14 for π.
a. 60 cu. in.
b. 188.4 cu. in.
c. 628 cu. in.
d. 1,884 cu. in.

Answer 1

Hello!

The formula for the volume of a cylinder is V = πr²h.

The problem gives us the height, which is 6 inches, and the radius, which is 10 inches. Since we have all the necessary values, we can substitute the lengths of the radius and height into our equation and solve for the volume. Also, remember that the problem states to use 3.14 for π.

V = (3.14)(10)²(6)

V = 3.14(100)(6)

V = 314 · 6

V = 1884

Therefore, the volume of this cone is 1,884 cubic inches, which is choice D.
