Solution

The correct option is C
$1000 c m^{3}$

We know that in a circle, the diameter is twice of a radius.

$\Rightarrow$ Diameter $= 2 \times$ radius

$= 2 \times 5 = 10 c m$

Cube of the diameter $= 10 \times 10 \times 10 = 1000 c m^{3}$

If the radius of a circle is 5 cm, find the value of the cube of its diameter.

The correct option is C 1000 cm3 We know that in a circle, the diameter is twice of a radius. ⇒ Diameter =2× radius =2×5=10 cm Cube of the diameter =10×10×10=1000 cm3

If the radius of a circle is $5 c m$ , find the value of the cube of its diameter.

The correct option is C
$1000 c m^{3}$

We know that in a circle, the diameter is twice of a radius.

$\Rightarrow$ Diameter $= 2 \times$ radius

$= 2 \times 5 = 10 c m$

Cube of the diameter $= 10 \times 10 \times 10 = 1000 c m^{3}$
