Question

find the area of the sector covered by the hour hand in 3 hours if the length of the hour hand is 7 cm.​

Answer 1

Answer:

$\frac{angle}{360} \times \pi \: {r}^{2}$

MINUTES COVERED IN 3 HOURS=180 MINUTES

THEREFORE ANGLE =180

$\frac{180}{360} \times \frac{22}{7} \times 7 \times 7$

=11×7

=77cm^2
