Question

The area of a circle is 3.14 square meters. What is the circle's radius?

Answer 1

Answer:

1 m

Solution,

Area=3.14 m^2

Radius=?

Now,

$area \: of \: circle = \pi \: {r}^{2} \\ \: \: \: \: or \: 3.14 = 3.14 \times {r}^{2} \\ or \: 3.14 = 3.14 {r}^{2} \\ or \: {r}^{2} = \frac{3.14}{3.14} \\ or \: {r}^{2} = 1 \\ or \: r = \sqrt{1} \\ r = 1 m$

hope this helps..

good luck on your assignment

Answer 2

A circle is a curve sketched out by a point moving in a plane. The radius of the circle whose area is  3.14 m² is 1 m.

What is a circle?

A circle is a curve sketched out by a point moving in a plane so that its distance from a given point is constant; alternatively, it is the shape formed by all points in a plane that are at a set distance from a given point, the centre.

The area of a circle is the product of the square of the radius and pi. Therefore, the radius of the circle with an area of 3.14 m² can be written as,

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

$3.14 = \pi r^2\\\\3.14 \times 3.14 \times r^2\\\\r = 1\rm\ m$

Thus, the radius of the circle whose area is  3.14 m² is 1 m.
