Question

If the area of ​​a circle is 3850 square then its circumference will be ?

Answer 1

Step-by-step explanation:

Area of circle = 3850 m²

πr² = 3850 m²

r² = 3850 × 7/22

r² = 1225

r = √1225 = 35 m

circumference = 2πr

=> 2×22/7 × 35 => 220 m

Answer 2

Answer:

Area of circle=3850 sq.m

$\pi \: { r}^{2} = 3850 \\ \frac{22}{7} \times {r}^{2} = 3850 \\ {r}^{2} = \frac{3850 \times 7}{22} \\ {r}^{2} = \frac{26950}{22} \\ {r }^{2} = 1225 \\ r = \sqrt{1225} = 35 \\ so \: radius = 35m$

$now \\ \: circumference \: of \: circle = 2\pi \: r \\ 2 \times \frac{22}{7} \times 35 = 44 \times 5 = 220m$
