Find the circumference of a trampoline with a diameter of 14 feet. Use π = 3.14.



Blank Space__________ft

To find the circumference of a trampoline, you can use the formula:

Circumference = π * diameter

Given that the diameter of the trampoline is 14 feet and π = 3.14, you can substitute these values into the formula:

Circumference = 3.14 * 14

Calculating the product:

Circumference = 43.96

Therefore, the circumference of the trampoline is 43.96 feet.

Find the circumference of a trampoline with a diameter of 14 feet. Use π = 3.14.



Blank Space__________ft

The circumference of a circle is calculated using the formula:

Circumference = π * diameter

Given that the diameter of the trampoline is 14 feet and π = 3.14, we can substitute these values into the formula:

Circumference = 3.14 * 14

Calculating the product:

Circumference = 43.96

Therefore, the circumference of the trampoline is 43.96 feet.

The Bay area of California was shaken by an earthquake on October 17, 1989. The epicenter was located at Loma Prieta. The diameter of the earthquake's horizontal waves that shocked the area measured about 120 miles. How many square miles were affected by this earthquake?



Blank Space__________square miles

To find the area affected by the earthquake, you can use the formula for the area of a circle:

Area = π * (radius)^2

Given that the diameter of the earthquake's waves is 120 miles, we can find the radius by dividing the diameter by 2:

Radius = 120 / 2 = 60 miles

Using π = 3.14, we can substitute the values into the formula:

Area = 3.14 * (60)^2

Calculating the product:

Area = 3.14 * 3600

Area = 11,304 square miles

Therefore, approximately 11,304 square miles were affected by the earthquake.

Solve the problem.



Find the radius of a circle that has a circumference of 28.26 feet.

To find the radius of a circle given its circumference, you can use the formula:

Circumference = 2 * π * radius

Given that the circumference of the circle is 28.26 feet and π = 3.14, you can substitute these values into the formula:

28.26 = 2 * 3.14 * radius

Simplifying:

28.26 = 6.28 * radius

To isolate the radius, divide both sides of the equation by 6.28:

radius = 28.26 / 6.28

Calculating the quotient:

radius ≈ 4.5 feet

Therefore, the radius of the circle is approximately 4.5 feet.
