How do you find the area of a circle d equals 4.5?
Area of a circle = pi*radius2 Area = 15.90431281 square units
Find the circumference and area of the circle if d equals 30 Use equals 3.14?
Diameter = 30. Radius = 15. Pi = 3.14. Circumference of the circle = d*pi = 30*3.14 = 94.2 units Area of the circle = pi*radius2 = 3.14*152 = 706.5 square units
Find the circumference and area of the circle if d equals 30 Use n equals 3.14?
The circumference of a circle is 2 * r * pi or d * pi; the diameter "d" = 2* the radius "r". "pi" is - VERY approximately! - 3.14. The area of a circle is pi * r^2. There is a calculator built into Windows, or you can use the calculator built into Google.
What is the area of a circle with D equals 14 mi?
The area of a circle is equal to pi times r2. If D is 14 miles, then r is 7 miles. Pi is approximately 3.14 and 72 is 49. So 3.14 x 49 = 153.86 square miles.
What is the formula to find the area of a circle with the diameter in it?
Area = Pi(d/2)2 where d = diameter
