Question

Find the area of a circle with diameter of 8cm use the value 3.14 for pie and do not round awnser

Answer 1

Step-by-step explanation

The area of a circle with a radius r is given by the following formula:

`A=\pi\cdot r^2`

In this case we know that the diameter is 8cm which means that its radius is 4cm. Using 3.14 for pie we get:

`\begin{gathered} A=3.14\cdot(4cm)^2 \\ A=3.14\cdot16cm^2=50.24cm^2 \end{gathered}`Answer

Then the answer is 50.24 cm².
