Exercise 26 Page 65

Use that $A = π r^{2}$ to find the area.

$0.01 π m^{2}$

Practice makes perfect

To find the area of a circle, we use the following formula.

A = π r^{2}

We know that this circle has a radius of

0.1

meters, so we can substitute

0.1

for

r

in the formula.

A = π r^{2}

$r = 0.1$

A = π \cdot 0.1^{2}

Calculate power

A = π \cdot 0.01

Multiply

A = 0.01 π

The area is

0.01 π m^{2} .
