hooray!The radius of a circle is 75 mm. What is the approximate area of the circle? Write your answer to the tenths place. Use 3.14 for π.(1 point)
mm2!!

Circumference = 2 * π * radius
Circumference = 2 * 3.14 * 38
Circumference = 2 * 3.14 * 38
Circumference ≈ 238.84 inches

Therefore, the approximate circumference of the circle to the nearest hundredths is 238.84 inches.

I apologize for the mistake. Let's correct that calculation:

Circumference = 2 * π * radius
Circumference = 2 * 3.14 * 38
Circumference = 6.28 * 38
Circumference = 239.92

Therefore, the approximate circumference of the circle with a radius of 38 inches is 239.92 inches to the nearest hundredths.

I apologize for the mistake in my previous responses. Let's correct the calculation one more time:

Circumference = 2 * π * radius
Circumference = 2 * 3.14 * 38
Circumference = 6.28 * 38
Circumference = 238.64

Therefore, the approximate circumference of the circle with a radius of 38 inches is 238.64 inches. Thank you for your patience.

To find the area of a circle, we use the formula:

Area = π * radius^2

Given:
Radius = 75 mm
π ≈ 3.14

Plugging in the values:

Area = 3.14 * (75)^2
Area = 3.14 * 5625
Area = 17677.5 mm^2

Therefore, the approximate area of the circle with a radius of 75 mm is 17677.5 mm^2.

I apologize for the mistake in the previous response. Let's correct the calculation for the area of the circle with a radius of 75 mm:

Given:
Radius = 75 mm
π ≈ 3.14

Area = π * radius^2
Area = 3.14 * 75^2
Area = 3.14 * 5625
Area = 17671.5 mm^2

Therefore, the approximate area of the circle with a radius of 75 mm is 17671.5 mm^2. Thank you for your patience.
