Question

The circle from above has radius r = 7.36 units. What is the area of the circle?

Answer 1

A = 170.09 square units

Step-by-step explanation:

To calculate a circle's area we use the formula:

• A = πr²

Where: A is the area, r is the radius.

Plug in the values:

• A = 3.14 × 7.36²
• A = 3.14 × 54.1696
• A = 170.09 units²

Therefore the area is 170.09 square units.

I have provided a diagram for better understanding..

`\setlength{\unitlength}{1cm}\begin{picture}(0,0)\thicklines\qbezier(2.3,0)(2.121,2.121)(0,2.3)\qbezier(-2.3,0)(-2.121,2.121)(0,2.3)\qbezier(-2.3,0)(-2.121,-2.121)(0,-2.3)\qbezier(2.3,0)(2.121,-2.121)(-0,-2.3)\put(0,0){\line(1,0){2.3}}\put(0.5,0.3){\bf\small7.36\ units}\end{picture}`
