Question

A museum groundskeeper is creating a semicircular statuary garden with a diameter of 25 feet. There will be a fence around the garden.The fencing costs $8.00 per linear hundredth. Use 3.14 for pie

Answer 1

we have that

The fence around the garden is equal to

$P=\frac{1}{2}\cdot\pi\cdot D+D$

where

pi=3.14

D=25 ft

substitute

$\begin{gathered} P=\frac{1}{2}\cdot3.14\cdot25+25 \\ P=64.25\text{ ft} \end{gathered}$

To find out the cost, multiply 64.25 ft by $8.00 per linear foot

so

64.25*8=$514

the answer is $514
