The radius of a circular board is 3.5 meters. If the cost of paint is $4/m squared, estimate the cost of painting the board

morpeh [17]

Answer:$154

Step-by-step explanation:

Given

the radius of the circular board is $r=3.5\ m$

The cost of paint is $\$4\ \text{per}\ m^2$

Area of circle $=\pi r^2$

Area of board

$\Rightarrow A=\pi r^2\\\\\Rightarrow A=\dfrac{22}{7}\times 3.5^2=38.48\ m^2$

Cost of painting

$\Rightarrow C=38.48\times 4=153.95\approx \$154$
