Question

Find the area of this circle use 3 for pi

Answer 1

Answer:

$A=300\operatorname{cm}$

Explanation: The answer can be simply found by substituting values in the area formula, which can be done as follows:

$\begin{gathered} A=\pi\cdot r^2 \\ r=10\operatorname{cm} \\ \therefore\rightarrow \\ A=\pi\cdot(10)^2=3\cdot10\cdot10=3\cdot100=300\operatorname{cm} \\ \therefore\rightarrow \\ A=300cm^2 \end{gathered}$
