Question

If a circle's circumpherence is 44 cm. Find the area of the circle. (step by step solution).​

Answer 1

Answer:

Circumference of circle = 2\pi r

Since we are given that the circumference of a circle is 44 cm

So, 44=2\pi r

22=pi r

22\times\frac{7}{22}= r

7= r

Area of circle = pi r^{2}

= 22/7*7^2

= 154 cm^2

Answer 2

Answer:

circumference of circle = 44cm

$2\pi \: r \: = 44$

$\pi \: r \: = 44 \div 2$

$22 \div 7 \times \: r \: = 22$

$r \: = 22 \times 7 \div 22$

r = 7 cm

area of circle =

$\pi \: {r}^{2}$

$22 \div 7 \times 7 \times 7$

154 cm sq.
