It depends what u have been told to use as pi
the formula is
A=r2pi
Area of a circle equals radius squared time pi
A circle with a 14 inch diameter has an area of 153.9 sq inches.
Assuming that the 14 inch box is square, you could fit a circle inside with a 14 inch diameter.
The area of a 14-inch circle is: 153.9 square inches.
The diameter of the circle is 14 units
The surface area of a sphere with a diameter of 14 inches is about 615.8 square inches.
A circle with a 14 inch diameter has an area of 153.9 sq inches.
Assuming that the 14 inch box is square, you could fit a circle inside with a 14 inch diameter.
diameter = circumference/pi
Area = 3.14*72 = 153.86 square inches
The area of circle that has diameter of 14 centimeters is: 153.9 cm2
The area of a 14-inch circle is: 153.9 square inches.
A circle with a diameter of 14 feet 9 inches has an area of: 170.87 square feet.
The area of a circle that has a diameter of 14 inches is: 153.9 square inches.
I assume that a 14 inch circle is a circle 14 ionches in diameter. Use the formula Area = Pi x radius of the circle X radius of the circle The radius is half the diameter. Pi is 3.14159 (appx) So the area = 3.14159 X 7 X 7 = 153.937 square inches. Or approximately 154 square inches
The area of a 14-inch circle is: 153.9 square inches.
The diameter of the circle is 14 units
It depends on what you mean by a "7-inch circle". If, as is normally the case, it is a circle with a 7-inch diameter, then you've got your answer in the question. If, unusually, you mean a circle with a 7-inch radius, then the diameter is twice that - 14 inches. If, even more unusually, you mean a circle with a circumference of 7 inches, then the diameter is 7/pi = 2.228 inches.
