Question

The angle subtended at centre by an arc of a circle is 50'. If the length of the arc is 5 पाई find the area of minor sector made by this arc of the circle Pi equal to 3.14

Answer 1

Answer:

Area is 14. 37

Step-by-step explanation:

Find the radius by arc length formula

l= theta/360*2pi*r

5=50/360*2pi*r

5=0. 87*r

5/0. 87=r

r=5. 74

Then calculate the Area by its formula

A=theta/360*pi*r^2

A=50/360*pi*(5. 74)^2

A=14. 37
