What is the area of a circle whose diameter is 20 cm?
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.
What is the area of a circle with a diameter of 2 cm?
Area = pi*12 = pi cm2
What is the radius of a 2 cm circle?
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.
What is the diameter of a circle whose area is 314 cm square?
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.
What is the area of a circle with 12cm as the diameter?
Area of circle is pi. r.r. Here r = diameter/2. r = 6 cm. area = 22/7 x 6 x 6 = 113.14 cm sq.
What is the area of a 28 cm circle using pi?
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
What is the area of a circle whose diameter is 20 cm?
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.
What is the area of a circle with a diameter of 6.4 cm?
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)
What is the diameter of a circle with an area of 254 cm?
Circle area = (pi)r2 = 254r2 = 254/pir = √254/pi ≈ 92r = diameter = 2(9) = 18 cm
What is the area of a circle with a diameter of 2 cm?
Area = pi*12 = pi cm2
What is the area of a circle with a diameter of 23cm?
Area = pi*r2r(radius) = diameter/2Radius = 23 cm/2= 11.5 cm-----------------now,Area = pi(11.5 cm)2= 415.5 cm2=========
