Find the arc length of the partial circle.

Serga [27]

Known :

r = 5 cm

θ = 360° - 90° = 270°

Asked :

Arc length of the partial circle = ...?

Answer :

Arc length

$= \frac{θ}{360} \times 2\pi r \\ = \frac{270}{360} \times 2 \times 3.14 \times 5 \\ = \frac{3}{4} \times 31.4 \\ = \frac{3}{4} \times \frac{314}{10} \\ = \frac{942}{40} \\ = 23.55 \: cm$

So, the arc length of the partial circle is 23,55 cm

Hope it helps and is useful :)

A clock shows a time of 3:20.what type of angle is this

fredd [130]

Hour hand: $\frac{35\pi}{18}$

Minute hand: $\frac{11\pi}{6}*\frac{3}{3}=\frac{33\pi}{18}$

$\frac{35\pi}{18}-\frac{33\pi}{18}\\\frac{2\pi}{18}\\\frac{\pi}{9}$

Acute angle
