Question

A.) 1,767.1 cm^3 B.) 235.6 cm^3 C.) 441.8 cm^3 D.)3,534.3 cm^3

Answer 1

Answer:

• A.) 1,767.1 cm^3

Step-by-step explanation:

As in the question we are given Radius of circle 7.5 cm and we need to the volume of the sphere.

Using formula:

$\dashrightarrow \: \: {\underline{\boxed{ \sf{Volume_{(Sphere)} = \dfrac{4}{3} \pi r^3 }}}}$

Substituting the required values:

$\\ \dashrightarrow \: \: { \sf{Volume_{(Sphere)} = \dfrac{4}{3} \pi \times (7.5)^3 }} \\ \\ \\ \dashrightarrow \: \: \sf Volume_{(Sphere)} = \frac{4}{3} \times \pi \times 421.875 \\ \\ \\ \sf \dashrightarrow Volume_{(Sphere)} = \frac{4}{3} \times \frac{22}{7} \times 421.875 \\ \\ \\ \dashrightarrow \sf Volume_{(Sphere)} = \frac{37125}{21} \\ \\ \\ \dashrightarrow \sf Volume_{(Sphere)} \approx1767.1 \: {cm}^{2}$

Hence,

• Volume of the sphere is 1,767.1 cm^3
