The formula for calculating the circumference of a circle is C = πd, where C is the circumference and d is the diameter.

Given that the diameter is 20, we can substitute this value into the formula:

C = 3.14 * 20 = 62.8

So, the approximate circumference of a circle with a diameter of 20 is 62.8 units.

The formula for calculating the circumference of a circle is C = πd, where C is the circumference and d is the diameter.

Given that the circumference is approximately 574 meters, we can rearrange the formula to solve for the diameter:

C = πd
d = C/π

Substituting the values given:

d = 574 / 3.14 ≈ 183.121

Rounding to the nearest tenth, the circle's diameter is approximately 183.1 meters.

The formula for calculating the circumference of a circle is C = 2πr, where C is the circumference and r is the radius.

Given that the radius is 38 inches, we can substitute this value into the formula:

C = 2 * 3.14 * 38 ≈ 238.36

Rounding to the nearest hundredths, the approximate circumference of the circle with a radius of 38 inches is 238.36 inches.

The formula for calculating the area of a circle is A = πr^2, where A is the area and r is the radius.

Given that the radius is 75 mm, we can substitute this value into the formula:

A = 3.14 * 75^2 ≈ 17671.25

Rounding to the tenths place, the approximate area of the circle with a radius of 75 mm is 17671.3 square millimeters.
