Question

A carnival equipment manufacturer states that the circular platform of a particular merry-go-round has an area of 3.14 square meters. What is the platform's radius?

Answer 1

The radius of the platform is 1 meter.

Explanation:

We are given the following in the question:

Area of circular platform of merry-go-round = 3.14 square meters.

We have to find the platform's radius.

Area of circular platform =

`A =\pi r^2`

where r is the radius of the platform.

Putting values, we get,

`\pi r^2 = 3.14\\\\r^2 = (3.14)/(3.14) = 1\\\\\Rightarrow r = 1\text{ meter}`

Thus, the radius of the platform is 1 meter.
