Reggie is cutting out buttermilk biscuits with a circular cutter. The cutter has a diameter of 6 centimeters. What is the cutter's radius?
The radius of the circular cutter is half of the diameter. Therefore, the radius is 3 centimeters.
Lorenzo bought a vegetarian pizza. It was served on a metal tray with a radius of 3 inches. What is the tray's area
The area of a circle is calculated using the formula A=πr^2, where A is the area and r is the radius.
Substituting the given values, we get:
A = π x 3^2
A = π x 9
A ≈ 28.27 square inches
Therefore, the tray's area is approximately 28.27 square inches.
Nick has a round trampoline with a radius of 2 yards. What is the trampoline's circumference?
The circumference of a circle is calculated using the formula C=2πr, where C is the circumference and r is the radius.
Substituting the given value, we get:
C = 2 x π x 2
C = 4π
Since π (pi) is a constant value approximately equal to 3.14, we can approximate the circumference as:
C ≈ 4 x 3.14
C ≈ 12.56 yards
Therefore, the trampoline's circumference is approximately 12.56 yards.
At Anthony's Laundromat, the circular opening of a washing machine has a radius of 1 foot. What is the opening's circumference?
The circumference of a circle is calculated using the formula C=2πr, where C is the circumference and r is the radius.
Substituting the given value, we get:
C = 2 x π x 1
C = 2π
Since π (pi) is a constant value approximately equal to 3.14, we can approximate the circumference as:
C ≈ 2 x 3.14
C ≈ 6.28 feet
Therefore, the opening's circumference is approximately 6.28 feet.
Which sign makes the statement true?
8.475 × 1010 0.0008475 × 1013
< (less than)
The number 8.475 × 10^10 can be written in scientific notation as 8.475E+10, and the number 0.0008475 × 10^13 can be written in scientific notation as 8.475E+10.
Comparing the two numbers, we can see that they have the same value but are written in different ways. Therefore, we can say that 8.475 × 10^10 < 0.0008475 × 10^13 is a true statement.
To find the radius of the cutter, you need to divide the diameter by 2. In this case, the diameter is given as 6 centimeters, so divide 6 by 2.
Radius = Diameter / 2
Radius = 6 cm / 2
Radius = 3 cm
Therefore, the cutter's radius is 3 centimeters.
