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.
| radius | | circumference | | area |
3 ft. __ ft. ft.^2
| radius | 3 ft. | circumference | 18.8 ft. | area | 28.3 ft^2 |
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.
| radius | | circumference | | area |
38 ft. __ ft. __ ft.^2
To find the circumference of a circle, you use the formula: circumference = 2 * pi * radius
Substitute the given values:
circumference = 2 * 3.14 * 38
circumference = 238.84 feet (rounded to the hundredths place)
To find the area of a circle, you use the formula: area = pi * radius^2
Substitute the given values:
area = 3.14 * 38^2
area = 3.14 * 1444
area = 4535.36 square feet (rounded to the hundredths place)
Therefore, for a circle with a radius of 38 feet:
- Circumference = 238.84 feet
- Area = 4535.36 square feet
thats not right choose another answer
My apologies for the error in the previous calculation. Let's correct it.
Given:
Radius = 38 ft
Circumference of a circle = 2 * pi * radius
Circumference = 2 * 3.14 * 38
Circumference = 239.32 ft (rounded to the hundredths place)
Area of a circle = pi * radius^2
Area = 3.14 * 38^2
Area = 3.14 * 1444
Area = 4538.16 ft^2 (rounded to the hundredths place)
Therefore, for a circle with a radius of 38 feet:
- Circumference = 239.32 feet
- Area = 4538.16 square feet
thats still wrong
I apologize for the oversight. Let's correct it.
Given:
Radius = 38 ft
Circumference of a circle = 2 * pi * radius
Circumference = 2 * 3.14 * 38
Circumference ≈ 238.76 ft
Area of a circle = pi * radius^2
Area = 3.14 * 38^2
Area = 3.14 * 1444
Area ≈ 4531.36 ft^2
Therefore, for a circle with a radius of 38 feet:
- Circumference is approximately 238.76 feet
- Area is approximately 4531.36 square feet
