Question

Q44- The radius of the sphere is 14cm find. T.S.A & volume

Answer 1

here is the answer please tell me the brilliant dancer

Answer 2

$\blue{\bold{\underline{\underline{Answer:}}}}$

$\green{\therefore{\text{T.S.A\:of\:sphere=2464\:cm}^{2}}}$

$\green{\therefore{\text{Volume\:of\:sphere=11498.66\:cm}^{3}}}$

$\orange{\bold{\underline{\underline{Step-by-step\:explanation:}}}}$

$\green{ \underline \bold{Given : }} \\ : \implies \text{Radius(r) = 14\: cm} \\ \\ \red{ \underline \bold{To \: Find : }} \\:\implies \text{T.S.A\: of \: sphere= ? }\\\\:\implies \text{Volume\: of \: sphere= ? }$

• According to given question :

$\bold{As \: we \: know \: that} \\ : \implies \text{T.S.A\: of \: sphere} =4\pi r^{2} \\ \\ : \implies \text{T.S.A\: of \: sphere} =4 \times \frac{22}{7} \times (14)^{2} \\ \\ : \implies \text{T.S.A\: of \: sphere} =4 \times 22\times 28 \\ \\ \green{ : \implies \text{T.S.A\: of \: sphere} = 2464\: {cm}^{2}}$

$\bold{As \: we \: know \: that} \\ : \implies \text{Volume \: of \: sphere} = \frac{4}{3} \pi {r}^{3} \\ \\ : \implies \text{Volume \: of \: sphere} = \frac{4}{3} \times \frac{22}{7} \times {14}^{3} \\ \\ : \implies \text{Volume \: of \: sphere} = \frac{4}{3} \times \frac{22}{7} \times 2744 \\ \\ : \implies \text{Volume \: of \: sphere} = \frac{241472}{21} \\ \\ \green{ : \implies \text{Volume \: of \: sphere} =11498.66 {cm}^{2} }$
