If the diameter of a round dinner plate is 10 inches what is the area of the plate
78.5 sq.cm
A = pi * r^2
A = 3.14 * 25
A = ?______ square inches
78 sq.cm
78.2 sq.cm
To find the area of a round dinner plate, we need to use the formula for the area of a circle. The formula is:
Area = π * radius^2
Given that the diameter of the dinner plate is 10 inches, we can find the radius by dividing the diameter by 2:
Radius = Diameter / 2
Radius = 10 inches / 2
Radius = 5 inches
Now, we can substitute the radius into the formula:
Area = π * (5 inches)^2
Area = π * 25 square inches
Since the value of π is approximately 3.14, we can calculate the area:
Area ≈ 3.14 * 25 square inches
Area ≈ 78.5 square inches
Therefore, the area of the round dinner plate is approximately 78.5 square inches.
