Question

The radius of a circle is 8cm then the area of quadrant of a cirlce isA) 52cmB) 44cmc) 54cmD). 48cm​

Answer 1

Answer:

D)48 cm

Step-by-step explanation:

Area of quadrant = (πr²)/4

Area = (3 * 8 * 8)/4 Considering pi = 3

Area = 192/4

Area = 48 cm²

Area = D)48 cm

Answer 2

${\huge{\pink{\underline{\underline{\purple{\mathbb{\bold{\mathcal{AnSwEr..}}}}}}}}}$

${\large{\blue{\bold{\underline{Given:-}}}}}$

• Radius of a circle = 8cm.

${\large{\blue{\bold{\underline{To\:Find:-}}}}}$

• Area of quadrant.

${\large{\blue{\bold{\underline{Formula\:Used:-}}}}}$

• Area of quadrant,

$\sf = \frac{1}{4} \pi \: r {}^{2}$

☆ So here area of quadrant,

$\sf = \frac{1}{4} \times \frac{22}{7} \times( 8cm ) {}^{2} \\ \\ \sf = \frac{1}{4} \times \frac{22}{7} \times \cancel 8 \: cm \times 8 \: cm \\ \\ \sf = \frac{352}{7} \: cm {}^{2} \\ \\ \sf = 50.28 \: cm {}^{2} \\ \\ \sf(approx)$
