MCQ
The diameter of a sphere is $14\ cm$. Its volume is :
- A$1428 \mathrm{~cm}^3$
- B$1439 \mathrm{~cm}^3$
- ✓$1437\frac{1}{3}\text{cm}^3$
- D$1440 \mathrm{~cm}^3$
✓
Answer
Correct option: C.
$1437\frac{1}{3}\text{cm}^3$
Diameter $= 14\ cm$
So, the radius $= 7\ cm$
Volume of the sphere $=\frac{4}{3}\pi\text{r}^3$
$=\frac{4}{3}\times\frac{22}{7}\times(7)^3$
$=1437\frac{1}{3}\text{ cm}^3$
So, the radius $= 7\ cm$
Volume of the sphere $=\frac{4}{3}\pi\text{r}^3$
$=\frac{4}{3}\times\frac{22}{7}\times(7)^3$
$=1437\frac{1}{3}\text{ cm}^3$
