Question

The area of a circle is 2464cm calculate it's diameter to 2

Answer 1

Answer:

The area of the circle is defined as

A=\pi r^2A=πr

2

Where, A=2464 cm² is the area,

r is the radius

Substituting the values,

2464=\frac{22}{7}\times r^22464=

7

22

×r

2

r^2=\frac{2464\times 7}{22}r

2

=

22

2464×7

r^2=784r

2

=784

r=\sqrt{784}r=

784

r=28r=28

Radius of the circle is 28 cm.

The diameter of the circle is D=2rD=2r

D=2\times 28D=2×28

D=56cm

Therefore, The diameter of the circle is 56 cm.The area of the circle is defined as
