Question

Find the arc length and area of the bold sector. Round your answers to the nearest tenth (one decimal place) and type them as numbers, without units, in the corresponding blanks below.

Answer 1

The answer is

length of arc=46.1 to 1d.p

Area of sector=507 to 1d.p

Explanation:

`arc \: length = (o)/(360) * 2\pi {r}`

l=240/360×2×22/7×11

`l = (116160)/(2520)`

L=46.1 to 1d.p

`area \: of \: sector = (o)/(360) * \pi {r}^(2)`

A=240/360×22/7×11²

`a = (638880)/(2520)`

a=507 to 1d.p
