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...

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 radius of a circle with a diameter of 15 cm?
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
What is the radius of a circle that has a 10 cm diameter?
diameter = radius × 2 → radius = diameter ÷ 2 = 10 cm ÷ 2 = 5 cm
If the diameter of a circle is 12 cm what is its radius?
Radius of a circle is half of its diameter and so 12/2 = 6 cm
If a circle has a diameter of 2 cm what is the radius of the circle?
1cm
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 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=========
Estimate the area of a circle with a diameter of 7 cm?
3848.451000 mm2 > 38.48451 cm 2
What is the area of a circle that has a diameter of 3 cm.?
Area of circle: pi*1.5^2 = 7.069 square cm rounded to three decimal places
Can you find the area of a circle if the diameter is 8 cm?
Yes, you can.
What is the area of a circle with the diameter 14.4 cm?
Area = pi*7.22 = 162.86 square cm to 2 decimal places
What is the radius of a circle with a diameter of 15 cm?
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
What is the area and circumference of a circle with a diameter of 15 cm?
Its circumference is: 15*pi cm Its area is: pi*7.5^2 square 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.
