Question

find the area of quadrant of a circle whose circumference is 44cm​

Answer 1

Answer:

The area of quadrant is 154cm^2

Answer 2

Step-by-step explanation:

Area of circle is 3.142*r^2

They have given the circumference means

pi =3.142

2 pi r = 44

r = 44/(2*3.142)

r=7.0019 cm

Now put this in área formula

Remember r^2=r*r

Área = pi r^2

Área =pi *r*r

Area=3.142*7.0019*7.0019

Area=154.04 meter square

This is area of full circle we have to find the area of quadrant

There are 4 quadrants so

To get the area of one quadrant divide the answer by 4

So area of quadrant is

Area = area of circle /4

Area=154.04/4

Area of quadrant =38.51 meter square
