How many square inches are in a 12 inches diameter circle?
area of circle is pi times diameter squared divided by 4 A = 3.14 x 12 x 12 /4 = 113 square inches
What is the area and circumference of a small circle 10 inches in diameter?
Area = Pi multiplied by the radius squared Circumference = Pi multiplied by the diameter r = 10 in./2 = 5 in. A = (3.1415)(5 in.)(5 in.) = 78.54 in.2 C = (3.1415)(10 in.) = 31.42 in. Therefore, a small circle with a diameter of 10 inches has an area of about 78.54 inches squared and a circumference of about 31.42 inches.
If the area of a circle is 20 square inches what is the diameter?
If the area of a circle is 20 square inches the diameter is: 5.046 inches.
The diameter of a circle is 9 cm What is the area of the circle?
pie x 4.5 squared
What is the area of a circle that has an 8.5 inch diameter?
The area of a circle that has an 8.5 inch diameter is: 56.75 square inches.
What is the area for a circle 7 inches in diameter?
It is: pi*3.5 squared inches
What is the area of a circle with a diameter of 6 in?
The formula for area of a circle is: A = (pi)*r^2 If the diameter of a circle is 6 then the circle's radius is 3. So, A = (pi)*(3)^2 A= 9*(pi) inches squared or A = 28.26 inches squared (rounded)
WHAT IS AREA OF 12 INCH DIAMETER CIRCLE?
Area of the circle: pi*6 squared = 36*pi square inches
What is the area of a circle with an 8 inch diameter?
The area of a circle with an 8 inch diameter is: 50.27 square inches. There are: pi*4 squared = 16*pi square inches or about 50 square inches
What is the area of a circle with diameter of 16 inch?
64*(pi) inches squared 200.96 inches squared rounded to two decimal places.
What is the area in square inches for a circle with the diameter of 7 inches?
It is: pi*3.5 squared = 38.485 square inches rounded
How do you find the area and perimeter of circle?
First you have to measure the diameter of the circle. The diameter is pi (pi is approximately 3.1415) times the diameter is the perimeter. Half the diameter is the radius and the area of a circle is pi times the radius squared. So for example, let us say that you have a circle with a diameter of 3 inches. The perimeter is then about 9.42 inches, and the area is about 7.07 square inches.
If The exact area of a circle is 81pi square inches what are the radius and diameter of the circle explain?
The radius is 9 inches because area of circle is pi*9 squared = 81pi square inches and the diameter is twice the radius which is 2*9 = 18 inches
What is the diameter of a circle that's area is 153.86in squared?
The diameter is approximately 7 inches.
How many square inches are in a 12 inch diameter circle?
Area of circle: pi*6 squared = 36*pi square inches
Area of a circle with 2 inch diameter?
In a circle, Area = pi times radius squared: A = (pi)(r^2) Since the diameter equals 2 inches, the radius is one inch: A = (pi)(1^2) A = pi = 3.14 inches squared
What is the area of a circle with a diameter of 10in.?
The area would be 78.53 squared inches. Formula: PI (x) Radius squared = Area Radius is half of the diameter of the circle. So the radius is 5 Inches. (10 divided by 2 = 5) 3.14 x 5 squared = Area ---> 3.14 x 25 = 78.53981634 Hope that helped
