the pizza shown has a radius of 13 cm what is the approximate area of the pizza (use 3.14 for “pie”)
To find the area of the pizza, we use the formula for the area of a circle:
Area = πr^2
Given that the radius (r) of the pizza is 13 cm, we can substitute this value into the formula:
Area = 3.14 x 13^2
Area = 3.14 x 169
Area ≈ 530.66 cm^2
Therefore, the approximate area of the pizza is 530.66 square centimeters.
the diameter of the pan is 12 inches what is the approximate circumference of a lid that will fit his frying pan? (use 3.14 for π)
The circumference of a circle is given by the formula:
Circumference = π x diameter
Given that the diameter of the pan is 12 inches, we can substitute this value into the formula:
Circumference = 3.14 x 12
Circumference = 37.68 inches
Therefore, the approximate circumference of a lid that will fit the frying pan is 37.68 inches.
on a circular playground the distance from its center to the edge of the playground is 38 feet what is the approximate circumference of the playground (use 3.14 for π)
The distance from the center of the circle (playground) to the edge is the radius. Given that the radius is 38 feet, we can find the circumference using the formula:
Circumference = 2πr
Substitute the radius (r) into the formula:
Circumference = 2 x 3.14 x 38
Circumference = 2 x 3.14 x 38
Circumference = 2 x 3.14 x 38
Circumference ≈ 238.84 feet
Therefore, the approximate circumference of the playground is 238.84 feet.
the diameter of the circle above is 6 cm what is the circumference of the circle
To find the circumference of a circle when the diameter is given, we use the formula:
Circumference = π x diameter
Given that the diameter of the circle is 6 cm, we can substitute this value into the formula:
Circumference = 3.14 x 6
Circumference = 18.84 cm
Therefore, the circumference of the circle with a diameter of 6 cm is approximately 18.84 cm.
the circle above has a radius of 4 cm what is the area of the circle
To find the area of a circle, we use the formula:
Area = πr^2
Given that the radius (r) of the circle is 4 cm, we can substitute this value into the formula:
Area = 3.14 x 4^2
Area = 3.14 x 16
Area = 50.24 cm^2
Therefore, the area of the circle with a radius of 4 cm is approximately 50.24 square centimeters.
