What is the area of a circle with diameter 30cm?
Area = π*d2 / 4 d = 30 cm => area = 706.86 sq cm
What is the area of a circle with diameter of 4.45 cm?
Area = (Pi/4)*diameter2 = .7854*4.452 = 15.5528 sq.cm.
What is the radius of a circle if is diameter 4 cm?

Its diameter is about 4 cm rounded
What is the area of a circle that has a diameter of 4 cm?
12.57 square cm.
What is the area of a circle with diameter 30cm?
Area = π*d2 / 4 d = 30 cm => area = 706.86 sq cm
If the radius of a circle is 4 cm what is the diameter?
Diameter: 2*4 = 8 cm
What is the area and circumference of a circle whose diameter is 4 centimeters?
Area = 12.6 cm2Circumference = 12.6 cm
How do you find the area of a circle that measures the diameter of 8 cm?
The formula for the area of a circle is: A = pi r2 where r is the measure of the radius. If the diameter of a circle is 8 cm, then the radius is half of that measure or 4 cm. Plug that into the formula and use 3.14 to approximate pi. A = 3.14(4)2 A = 3.14(16) Area is approximately 50.24 square cm.
What is the area of a circle with diameter of 4.45 cm?
Area = (Pi/4)*diameter2 = .7854*4.452 = 15.5528 sq.cm.
What is the area of a circle with a diameter of 1cm?
Diameter = 1 cm so radius = 1/2 cm Then area = π*r2 = 1/4*π or 0.7854 cm2 (approx)
What is the radius of a circle if is diameter 4 cm?
2 cm
Which has the greatest area a circle with a radius of 4 cm or a semi-circle with a diameter of 11 cm?
-7
What is area of a circle if diameter is 28 cm?
Area = 1/4*Pi*d2 = 0.25*3.14*282 = about 615.75cm2
