Question

A right cone is shown. The radius of the base is labeled x millimeters. The height is labeled forty millimeters. The slant height is labeled ninety millimeters. Find the value for the unknown measurement in the right cone. Round to the nearest tenth. Enter the correct answer in the box.

Answer 1

Answer:

Radius, x = 80.6mm

Step-by-step explanation:

$radius =\sqrt{height^2 -slant\ height^2} = \sqrt{90^2 - 40^2} = \sqrt{8100-1600} =\sqrt{6500}$

Radius = 80.6mm
