The circumference of a circle is 22pi inches. Find the area of that circle. Substitute 3.14 for

Question

pi. Express your answer to the hundredths place.(1 point)

Answer 1

Circumference = 2pi * r
22pi = 2 * 3.14 * r
22 = 6.28r
r = 22 / 6.28
r ≈ 3.50 inches

Area = pi * r^2
Area = 3.14 * (3.50)^2
Area = 3.14 * 12.25
Area ≈ 38.48 square inches

Therefore, the area of the circle is approximately 38.48 square inches.

Answer 2

Complete the table by finding the circumference and area of a circle with a radius of 3 feet. Substitute
3.14 for pi. Express your answers to the tenths place.(1 point)

Answer 3

Radius (ft) | Circumference (ft) | Area (sq ft)
-------------------------------------------------------------
3 | 18.8 | 28.3

Circumference = 2 * pi * r
Circumference = 2 * 3.14 * 3
Circumference = 18.84 ft (rounded to the tenths place)

Area = pi * r^2
Area = 3.14 * 3^2
Area = 3.14 * 9
Area = 28.26 sq ft (rounded to the tenths place)

Therefore, for a circle with a radius of 3 feet, the circumference is approximately 18.8 feet and the area is approximately 28.3 square feet.

Answer 4

Complete the table by finding the circumference and area of a circle with a radius of 38 feet. Substitute
3.14 for pi. Express your answers to the hundredths place.(1 point)

Answer 5

Radius (ft) | Circumference (ft) | Area (sq ft)
-------------------------------------------------------------
38 | 238.76 | 4536.46

Circumference = 2 * pi * r
Circumference = 2 * 3.14 * 38
Circumference = 238.76 ft (rounded to the hundredths place)

Area = pi * r^2
Area = 3.14 * 38^2
Area = 3.14 * 1444
Area = 4536.46 sq ft (rounded to the hundredths place)

Therefore, for a circle with a radius of 38 feet, the circumference is approximately 238.76 feet and the area is approximately 4536.46 square feet.

Answer 6

incorrect

Answer 7

I apologize for the error in the calculations.

For a circle with a radius of 38 feet:

Circumference = 2 * pi * r
Circumference = 2 * 3.14 * 38
Circumference = 239.52 feet

Area = pi * r^2
Area = 3.14 * 38^2
Area = 3.14 * 1444
Area = 4539.76 square feet

Therefore, the correct values for a circle with a radius of 38 feet are:

- Circumference: approximately 239.52 feet
- Area: approximately 4539.76 square feet

Answer 8

still wrong

Answer 9

Let's correct the calculations:

For a circle with a radius of 38 feet:

Circumference = 2 * pi * r
Circumference = 2 * 3.14 * 38
Circumference = 238.76 feet

Area = pi * r^2
Area = 3.14 * 38^2
Area = 3.14 * 1444
Area = 4532.16 square feet

Therefore, the correct values for a circle with a radius of 38 feet are:

- Circumference: approximately 238.76 feet
- Area: approximately 4532.16 square feet

Answer 10

thats incorrect

Answer 11

I apologize for the mistake in the calculations. Let's correct it:

For a circle with a radius of 38 feet:

Circumference = 2 * pi * r
Circumference = 2 * 3.14 * 38
Circumference = 238.76 feet

Area = pi * r^2
Area = 3.14 * 38^2
Area = 3.14 * 1444
Area = 4534.16 square feet

Therefore, the correct values for a circle with a radius of 38 feet are:

- Circumference: approximately 238.76 feet
- Area: approximately 4534.16 square feet
