Question

The area of a circle is 153.86 square meters. What is the diameter of the circle? Use 3.14 for π.

Answer 1

Answer:

Option (2). 14 m

Step-by-step explanation:

Formula to get the area of a circle 'A' = $\pi r^{2}$

where r = radius of the circle

Given in the question,

Area of the circle = 153.86 square meters

By putting the values in the formula,

153.86 = πr²

r = $\sqrt{\frac{153.86}{\pi } }$

r = $\sqrt{49}$

r = 7 meters

Diameter of circle = 2 × (radius of the circle)

                              = 2 × 7

                              = 14 meters

Therefore, diameter of the circle is 14 meters.

Option (2) is the answer.
