What is the area of a circle with a radius of 40cm?
A circle with a radius of 40 cm has an area of 5,026.55 square cm.
What is the radius of a circle with area of 40 square inches?
Radius = 3.57 inches.
Is a circle with a area of 40 more less or same than a circle with a radius of 4?
In order to even discuss this question, we must assume that the unit of the '40' is the square of the unit of the '4'. -- The radius, diameter, and circumference of the circle with an area of 40 are each 10.794% shorter than the corresponding measurement in the circle with radius = 4 . -- Its area (40) is 20.423% less than the area of the circle with the radius of 4 .
What is the area of a circle with the radius of 40 ft?
The area is 5,024 ft2. The formula for finding the area of a circle is: A = pi * r2 A for area. The r is for the radius. A = 3.14 * 40 ft2 A = 3.14 * 160 ft2 A = 5,024 ft2
If you had a cylinder a cone and a sphere with a radius of 20 feet and a height of 40 feet which would hold the most water?
the cylinder
Suppose the sphere below with radius r has a surface area equal to 40 units2 Find the surface area of the sphere with twice the radius?
160
What is the surface area of a cylinder with a radius of 30 centimeters and a height of 40 centimeters?
13,194.7cm2
What is the total surface area of this object who's radius is 2 and side is 8?
If it's a cylinder then its total surface area is: 40*pi square units
What is the area of a circle with a radius of 40cm?
A circle with a radius of 40 cm has an area of 5,026.55 square cm.
How many square miles in a 40 mile radius?
The formula for the area of a circle is: 3.14 (pi) times the radius squared. A circle with a 40 mile radius would have an area of 3.14 x 40 x 40 = 5024 square miles.
What is the radius of a circle with area of 40 square inches?
Radius = 3.57 inches.
What is the surface area of a cone with a slant height of 40 and a radius of 20?
A slant height of 20 and base circle radius (r) of 20 gives slant length (s) = 28.284 equation for cone surface area : (pi * r * s) + (pi * r2) = 1777.136 + 1256.637 = 3033.773 units2
Is 40 mile radius the same as 40 miles?
No, 40 mile radius is an area unit whereas 40 mile is distance. This means that something 30 miles from a location can be said to be in a 40 mile radius from that location.
Is a circle with a area of 40 more less or same than a circle with a radius of 4?

Find the height of a cylinder with a radius of 4 centimeter and the surface area is 72pi?
Think of the surface area of the cylinder in three parts. The top, the bottom, and the side. Surface area of the top and the bottom are easy, because the area of a circle is pi times the radius squared. Since the radius is 4, the area of the top and bottom are 16*pi each for a total of 32*pi. This means that the surface area of the "tube part" is 40*pi. {72 - 32 = 40} If you think of cutting this part, you can see that it's really just a rectangle. One side of the rectangle is the height of the cylinder, the other is the circumference of the base. The circumference is 2*pi*r, which here is 8*pi. Thus (8*pi)(height of cylinder) = (40*pi). Conclusion, the height of the cylinder is 5 cm.
What is the area of a circle with the radius of 40 ft?
The area is 5,024 ft2. The formula for finding the area of a circle is: A = pi * r2 A for area. The r is for the radius. A = 3.14 * 40 ft2 A = 3.14 * 160 ft2 A = 5,024 ft2
If you had a cylinder a cone and a sphere with a radius of 20 feet and a height of 40 feet which would hold the most water?
