The circumference of a circle is found by multiplying the diameter by π (pi).
Given that the diameter is 3.25 meters, we can find the circumference as follows:
Circumference = Diameter x π
Circumference = 3.25 meters x 3.14
Estimating the product to the hundredths place gives us:
Circumference ≈ 10.21 meters (rounded to the hundredths place)

The circumference of a circle can be found by multiplying the diameter by π (pi), or by multiplying the radius by 2π.
Given that the radius is 2.5 feet, we can find the circumference as follows:
Circumference = 2 x Radius x π
Circumference = 2 x 2.5 feet x 3.14
Estimating the product to the tenths place gives us:
Circumference ≈ 15.7 feet (rounded to the tenths place)
Given that the radius is 2.5 feet, we can find the circumference as follows:
Circumference = 2 x Radius x π
Circumference = 2 x 2.5 feet x 3.14
Estimating the product to the tenths place gives us:
Circumference ≈ 15.7 feet (rounded to the tenths place)
What is the area of a circle with a radius of 12 feet? Estimate the area to the hundredths place using 3.14 for π
The formula for the area of a circle is given by:
Area = π x (Radius)^2
Given that the radius is 12 feet, we can find the area as follows:
Area = 3.14 x (12 feet)^2
Simplifying the expression:
Area = 3.14 x 144 square feet
Calculating the product:
Area = 452.16 square feet
Estimating the area to the hundredths place gives us:
Area ≈ 452.16 square feet (rounded to the hundredths place)
Area = π x (Radius)^2
Given that the radius is 12 feet, we can find the area as follows:
Area = 3.14 x (12 feet)^2
Simplifying the expression:
Area = 3.14 x 144 square feet
Calculating the product:
Area = 452.16 square feet
Estimating the area to the hundredths place gives us:
Area ≈ 452.16 square feet (rounded to the hundredths place)
What is the area of a circle with a diameter of 10 millimeters? Estimate the area to the tenths place using 3.14 for π
.
.
The formula for the area of a circle is given by:
Area = π x (Radius)^2
Since the diameter is given and we know that the diameter is twice the radius, we can calculate the radius as half of the diameter.
Given that the diameter is 10 millimeters, the radius would be 10 mm / 2 = 5 mm.
Now we can find the area:
Area = 3.14 x (5 mm)^2
Simplifying the expression:
Area = 3.14 x 25 square mm
Calculating the product:
Area = 78.5 square mm
Estimating the area to the tenths place gives us:
Area ≈ 78.5 square mm (rounded to the tenths place)
Area = π x (Radius)^2
Since the diameter is given and we know that the diameter is twice the radius, we can calculate the radius as half of the diameter.
Given that the diameter is 10 millimeters, the radius would be 10 mm / 2 = 5 mm.
Now we can find the area:
Area = 3.14 x (5 mm)^2
Simplifying the expression:
Area = 3.14 x 25 square mm
Calculating the product:
Area = 78.5 square mm
Estimating the area to the tenths place gives us:
Area ≈ 78.5 square mm (rounded to the tenths place)
