Question

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

• A. $500c{m}^3$
• B. $1000c{m}^3$
• C. $2000c{m}^3$
• D. $200.5c{m}^3$

Answer 1

The correct option is B

$1000c{m}^3$

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

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

$=2\times 5=10cm$

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