Question

circumference of a circle is 44 cm. find the radius and area of circle. ([tex]\pi \frac{22}{7})

Answer 1

Step-by-step explanation:

circumference is 44

2pi r= 44

2×22/7×r= 44

r= 7cm

area of circle is pi r square

area is 44cm

Answer 2

SOLUTION:-

Given:

•Circumference of a circle is 44cm.

To find:

The radius & area of circle.

Explanation:

Circumference of circle: The distance around a circle on the other hand is called circumference of circle.

Formula: 2πr

Therefore,

=) 2πr= 44

$= > 2 \times \frac{22}{7} \times r = 44 \\ \\ \frac{44}{7} \times r = 44 \\ \\ r = \frac{44 \times 7}{44} \\ \\ r = 7cm$

Now,

Area of the circle: The area enclosed by a circle r is πr².

Formula: πr²

$= > \frac{22}{7} \times 7cm \times 7cm \\ \\ = > 22 \times 7cm \\ \\ = > 154 {cm}^{2}$
