Question

find the area of circle if circumfrance of circle is 154 cm

Answer 1

AREA=154
RADIUS sq. =154*7/22
R sq. =49
R=7
CIRCUMFERENCE=2*22/7*7=44 CM

Answer 2

☆Hello friend☆

$circumference = 2\pi \: r$

154 cm = 2 × 22/7 × r

154 cm × 7/ 22 × 1/2 = r

7 cm × 7 × 1/2 = r

24.5 cm = radius

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

Area = 22/ 7 × 24.5cm × 24.5 cm

= 22 × 3.5 cm × 24.5 cm

=1886.5 cm^2

Hope it helps
