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
What is the area of the circle d equals 100mm?
Area = pi*502
How do you find the area of a circle d equals 4.5?
Area of a circle = pi*radius2 Area = 15.90431281 square units
What is the area of a circle to the nearest whole number where d equals 14 in?
154 sq in
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

What is the area of circle to the nearest tenth d equals 23ft?
pi*11.52 = 415.4756284 or 415.5 ft to the nearest tenth
360 equals D in a C?
360 degrees in a circle
How do you express the area of a circle in terms of diameter?
Circle area = pi*r 2 r= D/2 Circle area = pi*(D/2) 2 = (pi/4)*D 2
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.
How do you find the diamter of a circle if you know the area?
In order to find the diameter of a circle if you have the area is to rearrange the formula for the area of a circle to put diameter as the unknown, like so: PIE*d = Area of a Circle d = (Area of a Circle) / PIE Therefore if the area of your circle is 40cm, 40/PIE = 12.73cm and that's the diameter.
What is diameter of circle with area 40 square inches?
Area of circle =(11/14) * d *d d denotes diameter. For your case answer is 7.1365 inches
What is the formula for finding the area of a circle when you know the diameter?
D=Diameter, pi=3.14159... Area of circle = (D/2)2 * pi
