Question

The radius of the circle is 3.12 m. calculate the area of the circle with regard to significant figures.

Answer 1

Answer:

$\text{The area of circle is }30.566 m^2$

Step-by-step explanation:

Given the radius of the circle 3.12 m.

we have to find the area of circle.

$\text{Area of circle is }\pi r^2$

where r is the radius of circle and

$\pi=3.14$

Area can be calculated as

$=3.14\times (3.12)^2$

$=30.566016 m^2\sim 30.566 m^2$

$\text{Hence, the area of circle is }30.566 m^2$
