Question

The radius is 2.1. What is the area of this circle? Round your answer to the nearest tenth. Use 3.14 for pi.

Answer 1

Answer:

Hey!

The area would be 13.85

Step-by-step explanation:-

Area of a circle's equation is π$r^{2}$ (pi $r^{2}$)

Since the radius is 2.1 and value of pi is 3.14cm,

area is

$2.1^{2}$ x 3.14

4.41 x 3.14

= 13.85

Answer 2

The area of this circle is 13.6.

What is the area of the circle?

Area of a circle is the region occupied by the circle in a two-dimensional plane.

The area of the circle is;

$\rm Area \ of \ circle=\pi r^2\\\\Where\ r =radius$

The radius is 2.1.

Substitute all the values in the formula

$\rm Area \ of \ circle=\pi r^2\\\\ Area \ of \ circle=3.14 \times 2.1^2\\\\ Area \ of \ circle=13.6$

Hence,  the area of this circle is 13.6.
