Question

What is the length (in terms of π) of the arc that subtends an angle of 36° at the centre of a circle of radius 5 cm?

Answer 1

Answer:

The length of Arc is π cm .

Step-by-step explanation:

Given :  

Angle subtended by an Arc , θ = 36°

Radius of circle, r = 5 cm

Length of Arc, l = (θ/360) × 2πr

l = (36°/360°) × 2 × π × 5

l = (1/10) × 10π

l = 10π/10

l = π cm

Length of Arc, l = π cm

Hence, the length of Arc is π cm .

Answer 2

$hi...$

$here \: is \: your \: answer...$

r = 5cm

Angle subtended= 36°

length of arc = ?

Length of arc =

Angle subtended / 360 × 2πr

$= \frac{36}{360} \times 2\pi(5)$

$= \frac{1}{10} \times 10\pi$

$= \pi \: cm$

$thus \: the \: length \: of \: ar c \: is \\ \: \pi \: cm.$

$hope \: this \: helps...$
