Question

Consider a sphere with radius 2.5. Determine its surface area and volume, and display them in separate lines. Make use of 'pi' defined in the 'math' module.

Answer 1

Answer:

$Surface \: Area= 4\pi \: {cm}^{2} \\\\ Volume= 20.83\pi \: {cm}^{3}$

Step-by-step explanation:

To find the surface area and volume of sphere.First write the formulas for both.

$\boxed{Surface \: Area \: = 4\pi {r}^{2} \: {unit}^{2}} \\ \\ \boxed{ Volume = \frac{4}{3} \pi {r}^{3} \: {unit}^{3} }$

Here Radius = 2.5 cm

$1)Surface \: Area \: = 4\pi {(2.5)}^{2} \: {cm}^{2} \\ \\ = 4 \times 6.25\pi \: {cm}^{2} \\ \\ Surface \: Area= 4\pi \: {cm}^{2} \\ \\ 2) Volume = \frac{4}{3} \pi {r}^{3} \: {unit}^{3} \\ \\ = \frac{4}{3} \pi( {2.5)}^{3} {cm}^{3} \\ \\ = \frac{4}{3}\pi \times 15.625 \\ \\ Volume= 20.83 \pi\: {cm}^{3}$

Hope it helps you.
