Formula and result of area of circle?
The formula for the area of a circle is: Area = (pi) x (Radius)2 . When you know the radius of the circle and you use it to calculate the area of the circle, the result will be equal to (pi) x (Radius)2 .
When radius is unknown then how to find area of a circle?
By dividing its diameter by 2 is equal to the radius of a circle and its area is pi*radius2
What is the radius of a circle if its circumference and area both equal 246?
A circle cannot have its circumference and area both equal to 246. The only possible equal values are circumference = 12.6 units area = 12.6 square units which are achieved by a circle with radius 2 units.
How does area of a circle relate to circumference?
The area of a circle is equal to the perimeter times half the radius. That is, A = P*r/2
What is the formula of area semicricle?
The area of a semicircle is one-half the area of a circle. it is equal to (pi/2)r^2, where r is the radius.
What is the area of a circle which has a radius equal to 1?
The area of a circle can be calculated using the formula pi*(radius^2). So in this case, the area of the circle will be pi*(1^2), which is equal to pi.
Formula and result of area of circle?
The formula for the area of a circle is: Area = (pi) x (Radius)2 . When you know the radius of the circle and you use it to calculate the area of the circle, the result will be equal to (pi) x (Radius)2 .
When radius is unknown then how to find area of a circle?
By dividing its diameter by 2 is equal to the radius of a circle and its area is pi*radius2
What does it mean when the circumference of the circle is equal to the area of a circle?
the radius of the circle is 2 units
What is the radius of a circle if the area is 64?
The area of a circle is (pi)(r^2). Set this equal to 64 and solve for the radius. r = sqrt(64/pi)
What is the area of a circle with a radius of 7 feet?
The area of a circle is equal to pi*r2, where pi is the radius. In this case, the area is equal to pi*(7 feet)2, which is about 154 square feet.
What is the radius of a circle if its circumference and area both equal 246?
A circle cannot have its circumference and area both equal to 246. The only possible equal values are circumference = 12.6 units area = 12.6 square units which are achieved by a circle with radius 2 units.
What is the radius of a circle which has equal numeric values for the circumference and the area?
r = 2
How does area of a circle relate to circumference?
The area of a circle is equal to the perimeter times half the radius. That is, A = P*r/2
What is the formula using pi for the area of a circle?
area of a circle is equal to pi times the square of its radius.. A=(pi)r^2
What is the area of 45mm diameter circle?
The area (A) of a circle is A = π . r2 The diameter (D) is equal to D = r / 2 . Were r is the radius. If the diameter of the circle is 45 mm, and we divide it by 2. We will obtain the radius which is equal to 22,5mm: D = 45mm / 2 = 22,5mm If we square this radius the result is 506,25mm2: r2 = (22,5mm)2 = 506,25mm2 So the area of the circle of diameter 45mm is: A = 506,25mm2 . π = 1590,43mm2d
What is the formula of area semicricle?
The area of a semicircle is one-half the area of a circle. it is equal to (pi/2)r^2, where r is the radius.
