Question

A clock's minute hand travels one full circle each hour. A particular clock's minute hand is 10.2 cm. What is the approximate area covered by that minute hand in 3 hours? Use 3.14 for π . 192.17 cm² 326.69 cm² 980.06 cm²

Answer 1

Answer: 980.06 cm²

Step-by-step explanation:

We need to find the area of a full circle with radius 10.2 cm

A = pi*r^2

A = 3.14*(10.2)^2

A = 326.6856

This is the approximate amount of area the minute hand covers in 1 hour.

In 3 hours, it covers 3 times that amount.

3*326.6856 = 980.0568

That rounds to 980.06

Answer 2

Answer: The answer is 980.06 cm2
