Answer:
The diameter of Pool A is 14.64 meters. So, the diameter of Pool B is greater, and the circumference is greater by 0.56 meters.
Explanation:
Identify the diameter of Pool A.
d = 2r
d = 2(24) Substitute 24 for r.
d = 48 ft
Convert from feet to meters. Use the ratio of 1 foot to 0.305 meters. Round to the nearest hundredth.
48 × 0.305 = 14.64
The diameter of Pool A is about 14.64 meters.
Use the formula to find the circumference of Pool A.
C = πd
C = π(14.64) Substitute 14.64 for d.
C ≈ 3.14(14.64) Substitute 3.14 for π.
C ≈ 45.97 Multiply.
The circumference of Pool A is about 45.97 feet.
Identify the diameter of Pool B.
d = 14.82 m
The diameter of Pool B is 14.82 meters.
Use the formula to find the circumference of Pool B.
C = πd
C = π(14.82) Substitute 14.82 for d.
C ≈ 3.14(14.82) Substitute 3.14 for π.
C ≈ 46.53 Multiply.
The circumference of Pool B is about 46.53 feet.
The circumference of Pool B is greater than the circumference of Pool A.
Find how much greater the circumference of Pool B is compared to the circumference of Pool A.
46.53 − 45.97 = 0.56
The circumference of Pool B is greater than the circumference of Pool A by about 0.56 meters.
