Question

Find the volume and surface area of a sphere of radius 14 cm.

• A. volume:34,212 & surface area:2364
• B. volume:32,112 & surrface area:2564
• C. volume:34,496 & surface area:2464
• D. volume:33,333 & surface area:2400

Answer 1

The correct option is C volume:34,496 & surface area:2464

que. Find the volume and surface Area of u

sphere of radius 14 cm.

$\to$ volume of sphere is $\frac{4}{3}\pi r^3$

So, volume of sphere $=\frac{4}{3}\times \pi \times r^3$

$=\frac{4}{3}\times \pi \times (14{)}^3$

$=34,496$

$\to$ surface Area of sphere is $=4\pi r^2$

So, surface of sphere $=4\pi r^2$

$=4\times \pi \times (14{)}^2$

$=2464$
