Step-by-step explanation:
Answer above
Area of a circle = pi x r^2
A = pi x (3)^2
A = pi x 9
A = 9pi ft^2 = 28.27 ft^2

Answer:
26.7pounds
Step-by-step explanation:
Suppose that an individual has a body fat percentage of 15.9% in weighs 168 pounds
This is calculated as:
Pounds of his weight that is made up of fat is calculated as
Body fat percentage × Body weight in pounds
= 15.9% × 168 pounds
= 15.9/100 = 168 pounds
= 26.712 pounds
Approximately to the nearest tenth = 26.7 pounds
Correct question is;
Terry is filling spherical water balloons with a faucet that puts out 100 cm³ of water per second. At that rate, it takes Terry 6 seconds to fill a balloon. What is the radius of a filled balloon?
Answer:
r = 5 cm
Step-by-step explanation:
Volume of a sphere is;
V = (4/3)πr³
It takes 6 seconds to fill the balloon when a faucet that puts out 100 cm³ of water per second.
Thus,
Volume of balloon = 100 × 6 = 600 cm³
Thus;
(4/3)πr³ = 600
r³ = (600 × 3)/4π
r³ = 143.239
r = ∛143.239
r = 5.23
Approximation to the nearest whole number gives; r = 5 cm
Answer:
x ≥ 3.
Step-by-step explanation:
A minimum of 3 means 3 or more than 3, so it's
x ≥ 3.
