Question

if the circumference of a circular sheet is 154 m find its radius also find the area of the sheet( take arc 22/7) guve answer in detail ?​

Answer 1

$\huge{\mathfrak{\blue{\underline{Answer}}}}$

First the radius of the circle :

$154cm = 2\pi \: r \\ 154cm = 2 \times \frac{22}{7} \times r \\ r = \frac{154cm \times 7}{2 \times 22} \\ r = \frac{49}{2} cm \\ r = 24.5cm$

Area of the circle :

$= \pi \: r {}^{2} \\ = \frac{22}{7} \times 24.5cm \times 24.5cm \\ = 1886.5cm {}^{2}$

Answer 2

Answer:

solved

Step-by-step explanation:

r = 154/2π = 154x7/44 =49/2 m.

area = πr² = 22/7(49²/4) = 1886.5 m²
