MCQ
The radius of a sphere is 2r, then its volume will be:
- A$\frac{8\pi\text{r}^3}{3}$
- B$\frac{4}{3}\pi\text{r}^3$
- C$\frac{32}{3}\pi\text{r}^3$
- D$4\pi\text{r}^3$
✓
Answer
- $\frac{32}{3}\pi\text{r}^3$
Solution:
Volume of sphere $=\frac{4}{3}\pi\text{r}^3$
$=\frac{4}{3}\pi(\text{2r})^3$
$=\frac{4}{3}\pi\text{8r}^3$
$\frac{32}{3}\pi\text{r}^3$
