The formula of finding the area of a circle is: pi(r)^2 or pi(d/2)^2
Cuz r = d/2
So when d = 2, r = 2/2 = 1
pi(1)^2 = pi(1) = pi = 3.14...
Area of a circle = pi R2 R = radius = 1/2 of the diameter Area = pi (3.2)2 = 10.24 pi = 32.1699 square cm(rounded)
The diameter of a circle is twice its radius. Thus the radius of a circle is half its diameter. → a circle with a diameter of 15 cm has a radius of 15/2 cm = 7.5 cm
Area of a Circle (A) = pi times the radius (r) squared A = (pi) (r)2 Diameter of a Circle (d) = 2 times the radius (r) d = 2r First, find the r Since the diameter (d) = 70 cm, then 70 cm = 2 r (70 cm)/2 = r r = 35 cm Now that you have found the value of the radius (r), you can plug in r for the equation for the area (A) of a circle: A = (pi) (35 cm)2 A = (pi) 1225 cm2 At this point you can multiply 1225 cm2 by pi with a calculator to get the value of 3848.45100065 which can be simplified to 3848.5 cm2
The radius of a circle is half the length of its diameter. Therefore, if the diameter of the circle is 10 cm, the radius would be half of that, which is 5 cm. The formula to find the radius of a circle is r = d/2, where r is the radius and d is the diameter.
Radius of a circle is half of its diameter and so 12/2 = 6 cm
The area of a circle with a diameter of 28 cm is pi*(d/2)2= 615.8 cm2 The area of a circle with a diameter of 28 cm is pi*(d/2)2= 615.8 cm2 The area of a circle with a diameter of 28 cm is pi*(d/2)2= 615.8 cm2 The area of a circle with a diameter of 28 cm is pi*(d/2)2= 615.8 cm2
The area of a circle can be calculated using the formula A = πr^2, where r is the radius of the circle. Since the diameter is twice the length of the radius, the radius of a circle with a diameter of 6 cm is 3 cm. Plugging this value into the formula, we get A = π(3)^2 = 9π cm^2. Therefore, the area of a circle with a diameter of 6 cm is 9π square centimeters.
The formula to calculate the area of a circle is A = πr^2, where r is the radius of the circle. Since the diameter is 20 cm, the radius would be half of that, which is 10 cm. Plugging in the radius into the formula, we get A = π(10)^2 = 100π cm^2. Therefore, the area of the circle with a diameter of 20 cm is 100π square centimeters.
Area of a circle = pi R2 R = radius = 1/2 of the diameter Area = pi (3.2)2 = 10.24 pi = 32.1699 square cm(rounded)
Circle area = (pi)r2 = 254r2 = 254/pir = √254/pi ≈ 92r = diameter = 2(9) = 18 cm
Area = pi*12 = pi cm2
Area = pi*r2r(radius) = diameter/2Radius = 23 cm/2= 11.5 cm-----------------now,Area = pi(11.5 cm)2= 415.5 cm2=========
3848.451000 mm2 > 38.48451 cm 2
Area of circle: pi*1.5^2 = 7.069 square cm rounded to three decimal places
The radius of a circle is half the diameter, so if the circle has a diameter of 2 cm, the radius would be 1 cm.
Yes, you can.
To find the diameter of a circle with a given area, you first need to calculate the radius using the formula for the area of a circle: A = πr^2. Given that the area is 314 cm^2, you can rearrange the formula to solve for the radius, which would be √(A/π). Plugging in the area, you get √(314/π) ≈ 10 cm. Finally, to find the diameter, you double the radius, resulting in a diameter of approximately 20 cm.
