How do you Find the area of the circle use the pie of 3.14?
You use the formula: area = pi x radius squared If you approximate pi with 3.14, and replace the square with a product, that becomes: area = 3.14 x radius x radius
What is the area of a circle with a diameter of 10 feet?
The area of a circle = (pi) x radius squared radius = 1/2 diameter 3.14 x 5 feet squared 3.14 x 25 = 78.5 square feet
What is the area of a circle with radius 5 centimeters?
Area = pi R2 = 25 pi = 78.54 square centimeters(rounded)
What is the area of a circle whose equation is x squared plus y squared -10x plus 6y -15 equals 0?
Equation: x^2 +y^2 -10x +6y -15 = 0 Completing the squares: (x-5)^2 +(y+3)^2 -25 -9 -15 = 0 So: (x-5)^2 +(y+3)^2 = 49 which is the radius of the circle squared Area of the circle: 49*pi = 154 square units rounded to the nearest integer
What is the area of a circle with a diamter of 16cm?
64 pi ie just over 201 sq cm
What is the area of the circle if the radius is 5?
The area of a circle is equal to pi times the radius squared. So in your case it would be 5 squared, (25) times pi which is equal to ~78.5
If the area of a circle is 25 square units what is the radius of the circle?
area equals pi r squared therefor r squared equals area over pi. Now find square root of r squared and you have "R" (radius) = 2.821
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
What is the circumference of a circle that has an area of 25 centimeters squared?
The circumference of a circle that has an area of 25 centimeters squared is about 17.72 cm
What is the area of a circle with a radius of 25 cm?
A circle with a radius of 25 cm has an area of 1,963.5 square cm.
The area of a circle with a radius of 5?
Formula for finding the area of a circle = pie times the radius squared ( 3.14 x 52 ) 3.14 x 25 = 78.5 (do not forget the units whether it be centimeters, inches, etc. they are squared as well. i.e. 78.5 cm2)
How many square feet in a 1 foot diameter circle?
The area of a circle is PI times the radius of the circle squared. The radius of a one foot diameter circle it 1/2 or .5 feet. .5 squared is .25 PI is 3.1416 3.1416 times .25 = .79 square feet So, there are about .8 square feet in a 1 foot diameter circle.
What is the area growth from 3 mile radius to a 15 mile radius?
Area variesa s pi times the radius squared. 15/3 = 5; 5 squared = 25 A radius of 15 miles grows the area 25 times
Find the area of a circle whose radius is 25 inches?
Area = Pi(r)2 - A circle with a radius of 25 inches has an area of 1,963.5 square inches.
What is the radius for a circle with the equation x squared y squared 25?
Equations of circles are usually in x2+y2=(radius)2 form, so if you have x2 + y2 = 25 x2 + y2 = 52 then radius = 5.
Connection between the circumference and the diameter of a circle?
Divide the diameter by 2, this will give you the radius. multiply the radius by the radius, this gives you the radius squared. Multiply the raduis squared by Pi (3.14) to get the circumference. Formula : Circumfrence = Pi X R squared so, if the diameter is 10, the radius is 5, the radius squared is 25, 25 X 3.14= circumference
What radius area of circle is 25 cm?
If you mean area of a circle with a radius of 25 cm then it is:- Area = pi*252 = 1963.495 square cm to 3 decimal places
