What is the circumference of a circle if the diameter is 40 inches?
The circumference of a circle, if the diameter is 40 inches, is about 125.7 inches. (C = d x Pi).
What is the circumference of a circle circumscribed about a square with a perimeter of 40?
Assuming you mean that the circle is touching all 4 corners of the square: If the perimeter of the square is 40, then each side of the square is 10 (40/4=10). You could find the diameter of the circle by breaking the square up into 2 triangles, drawing a diagonal line through the square. Using pythagorean's theory (a^2+b^2=c^2), we know legs 2 and b (they are each one side of the square, so: (10^2+10^2=c^2). 10^2 is 100, therefore it is (100+100=c^2). (200=c^2) (√200=c) and the √ of 200 is about 14.142, meaning that the diameter of the circle is √200, which is the same as 10√2, (or approximately 14.142). You multiply the diameter of a circle by pi to get the circumference of a circle. Therefore, the exact answer is (10√2)(π), which would be approximated at 44.42882938158366247015880990 units, where π is pi.
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 circumference of a circle with a diameter 40 FEET?
The circumference of a circle can be calculated using the formula C = πd, where C is the circumference, π is a constant approximately equal to 3.14159, and d is the diameter of the circle. Given a diameter of 40 feet, we can plug this value into the formula to find the circumference: C = π(40) = 3.14159(40) = 125.6636 feet. Therefore, the circumference of a circle with a diameter of 40 feet is approximately 125.66 feet.
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.
How many square feet are in a circle 40 feet in diameter?
1256.64 square feet
How many square feet in a 40' diameter circle?
Area of circle: pi times radius squared
How many square inches in a 40 diameter circle?
400 x pi squinches
What is the area of the circle if the diameter is 40 inches inches?
The area of the circle is 1,256.6 square inches.
If a circle has the diameter of 40 in what is the area?
Area of circle: pi*20^2 = 400*pi square units
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 diameter of 1000 sq ft circle?
The diameter is twice the square root of (1000/pi) feet.
How many square inches in a 40 inch diameter circle?
Area of a circle = πr² (remember that r or radius is exactly half of the diameter) Radius therefore = 40/2 = 20 inches Thus the Area = 3.14159 × 20 squared = 1256.636 square inches
How square feet in a 40 inch diameter circle?
Area of circle: pi*(20/12)^2 = 8.727 square feet rounded to 3 decimal places
How many square feet are in a 40 foot diameter circle?
Oh, dude, you're hitting me with some math here! So, the area of a circle is π times the radius squared. If the diameter is 40 feet, the radius is 20 feet. Plug that into the formula, and you get an area of 400π square feet. But who's really counting, right?
What is the area of a circle with a diameter of 40 ft?
Area = pi*202 = 1256.637 square feet to 3 d.p.
What is the diameter of a 40 centimeter circle?
40 centimeters. The size of a circle is typically stated by giving its diameter. The circumference of a 40 cm circle (distance around the outside) is 40 x pi or about 125.66 cm.
