Question

the circumference of a circle is 220 cm Find the area of the circle​

Answer 1

Answer:–

Area of the circle = 3850 cm²

~~~~~~~~~~~~~~~~~~

Explanation:—

Given:

Circumference of circle = 220cm

Circumference of circle = 2πr

.

$\Longrightarrow\:220\:=\:2\:×\:\dfrac{22}{7}\:×\:r$

$\Longrightarrow\:r\:=\:220\:×\:\dfrac{7}{22}\:×\:\dfrac{1}{2}$

$\Longrightarrow\:r\:=\:5\:×\:7$

$\fbox\orange{Therefore, \:r\: =\: 35 \:cm²}$

______________

Area of circle = πr²

$\dfrac{22}{7}\:×\:35\:×\:35$

$=\:22\:×\:5\:×\:35$

$\fbox\orange{=\:3850 \:cm²}$

Therefore, the area of the circle = 3850 cm²
