Question

A large clock on a county courthouse has a circumference of about 25 feet. The minute hand extends from the center of the clock to the edge of the clock. How long is the minute hand?

Answer 1

Minute hand = 3.98 feet

Explanation:

Circumference of a circle can be calculated by

C = 2 x pi x radius

The minute hand extends from center to the edge means that minute hand is the radius and that is required.

putting values in above equation

C = 25 and pi = 3.14

25 = 2 x 3.14 x radius

radius = 25 / 6.28

Radius = 3.98 feet
