Question

The radius of the circular base of a cone measures 2.6 inches, and its slant height measures 1.5 inches.

What is the approximate lateral area of the cone?

Use π≈3.14.

Enter your answer rounded to the nearest tenth in the box.

Answer 1

11.6 sq. inches

Explanation:

The lateral area of a cone can be found using the formula:

L = πrℓ

where r is the radius of the circular base and ℓ is the slant height.

Substituting in the given values, we have:

L = 3.14 x 2.6 x 1.5

L ≈ 11.6

Rounding to the nearest tenth, the approximate lateral area of the cone is 11.6 square inches.
