Question

susan has a circular koi pond in a square patio with sides measuring 30 feet each. Find the area of the shaded region to the nearest hundredth.use 3.14 for pi

Answer 1

The side of the square patio will equal the diameter of the circular pond.

d=30 .

Half of the diameter is the radus

30/2 = 15 . r=15

Area of a circle is A=
`\pi r^(2)` .

Plug in the values A = (3.14)(15)^2 = 706.50 ft squared
