Question

What is the área of a circle with a radius of 7 m?A. 153.86 m2B. 49 m2C. 128.12 m2D. 200.96 m2

Answer 1

The area of a circle is defined as

`A=\pi(r)^2`

Where r is the radius, and pi is 3.14.

`\begin{gathered} A=3.14(7m)^2 \\ A=3.14\cdot49m^2 \\ A=153.86m^2 \end{gathered}`

Hence, the solution is A.
