What is the area of a circle if the diameter is 400 feet?
Area = pi times radius2 where radius = 200 feet therefore area = pi times 2002 Area = 125 663.7 feet2
What is the diameter of a circle is the area is 400pie?
area = pi x diameter squared/4 = 400 pi diameter squared = 4 x 400 x pi/pi = 1600 diameter = sqrt 1600 = 40
What is the area of a circle with a 200 foot radius?
r=200 ftd= 400 ftc= πd= 3.14 x 400c= 1256fta= πr²r² = 40, 000.... (remember always do the indicies first because of B.I.D.M.A.S)3.14 x 40, 000AREA = 125, 600 ft²:)
A square has an area of 400 centimeters what is the length of one of the sides?
The area of the square cannot be 400 centimetres - it must be 400 square centimetres.If the area is 400 sq cm, then each side is sqrt(400) = 20 cm.
How many square miles in a 400 mile radius?
It is 502655 sq miles, approx.
If a circle has area of 400 square units then what is the radius?
If a circle has area of 400 square units then its radius is: 11.25 units.
If the radius of a circle is doubled what happens to the area of the circle?
the area of the circle is increased by 400%
If a circle has an area of 400 cm find the radius to the nearest tenth?
r = sqrt(400/pi) = 11.3 cm
What is the area of a circle with a radius of 20?
400 pi
What is the area of a circle with the radius of 20 inches?
Using 3.14 as Pi the area of circle is: 1256.0
Find the area of a circle with the diameter of 40m?
The area of a circle is (pi) times (the radius)2. The radius of the given circle is 1/2 of the diameter = 20m. Area = (pi) times (20)2 = 400(pi) = 1,256.64 square meters(rounded)
What is the area of a circle if the radius is 20in?
Area = pi R2 = 400 pi = 1,256.64 square inches
What is the area of a circle whose radius is 20 meters?
Using 3.14 as Pi the area of circle is: 1256.0
A sector of a circle has a central angle of 400 and an area of 300 cm2. Find the radius of the circle?
To find the radius of the circle, we first need to determine the radius of the sector. The area of a sector is given by the formula A = 0.5 * r^2 * θ, where A is the area, r is the radius, and θ is the central angle in radians. In this case, the central angle is 400 degrees, which is approximately 6.98 radians. Plugging in the values, we get 300 = 0.5 * r^2 * 6.98. Solving for r, we find that the radius is approximately 7.67 cm.
Find Circumference of a circle if the area is 400π m2?
pi*r2 = 400*pi Therefore radius = 20 meters Cicumference = 2*pi* radius = 40*pi meters
How many Square miles in 400 mile radius?
area circle = π × radius² = π × (400 miles)² = 160000π sq mi ≈ 502655 sq mi
