Given:

Height = 5 inches

Radius = 3 inches

Determine the lateral area of the cone.

Formula for the lateral area of the cone:

L. S. A=πrh

Solution:

Substitute the given values to the formula for the lateral surface area of the cone.

L. S. A=πrh

L. S. A=π(5 inches)(3 inches)

L. S. A=15 π in^2

L. S. A = 47.12 in^2

Final answer:
L. S. A=47.12 in^2
