A homeowner wants to include a semicircular patio at the end of a square sandbox. She knows that the area of the semicircular pa
tio is 25.12 cm. What is the length of the side of the square?
1 answer:
Answer:
8cm
Step-by-step explanation:
First you must know that the diameter of the semi-circular patio is equal to the length of one side of the square
Area of a semi circle = πr²/2
25.12 = πr²
25.12 = 3.14r²/2
r² = 25.12(2)/3.14
r² = 16
r = √16
r = 4
Get the diameter
d = 2r
d =2(4)
d = 8cm
Hence the length of the side of the square is 8cm
