d = 28.3
Divide the diameter by 2, to get the radius. Then use the formula for the area of a circle:area = pi x radius squared
Circumference = pi*d So d = circ/pi = 200/pi = 63.662 units
First of all, you have to promise us that you're talking about a circle.We're going to assume that, since you mentioned 'radius'.The perimeter of a circle ... usually called its 'circumference' ... is (pi) x (the circle's diameter).The circle's diameter is (2) x (its radius).Diameter = 200 millimetersCircumference = (pi) x (200) = 628.319 millimeters (rounded)
There are: pi*100*100 square yards
1) First, Measure the Diameter. The diameter is the distance across a circle. It can be be seen as cutting a circle in half. 2) When the diameter is too large to determine, estimate the radius. The radius can be seen as half of the diameter. Once you picture the radius, multiply it by 2. 3) Now you may find the Circumference. Once you find the Diameter of a circle, you multiply it by pi. Pi is the value of 3.14 . Once you multiply the Diameter by pi, you find the Circumference! For example, if a jogger estimated diameter of a circular path as 200 meters across, then circumference would be 200 times 3.14 . 4) Make sure to verify your units of measurement. If your Diameter is in meters, your circumference must be in meters also. You just found the Circumference of a circle!!!
A circle with an area of 200 acres has a diameter of: 3,331 feet.
Oh, dude, like, the area of a circle is π times the radius squared, right? So, if the diameter is 200 m, the radius is half of that, which is 100 m. Just plug that into the formula, and you get an area of 31,415.93 square meters. Easy peasy, lemon squeezy.
Using 3.14 as Pi the area of circle is: 31400.0
Divide the diameter by 2, to get the radius. Then use the formula for the area of a circle:area = pi x radius squared
Using 3.14 as Pi the area of circle is: 31400.0
Divide the diameter by 2 to get the radius. Then use the formula for the area of a circle: area = pi x radius2.
the sq. footage of the circle would be 3.14(radius squared). if the diameter is 200ft, then the radius is 100ft. So, 3.14(100x100)= 3.14(10,000)= 31,400 sq. feet
100. The radius is 1/2 of the diameter.
Its diameter will be: 2*100 = 200 miles
Area = pi times radius2 where radius = 200 feet therefore area = pi times 2002 Area = 125 663.7 feet2
It is 100 units.
Area = pi * radius2 628mm2 = 3.14 * radius2 dividing by pi (approximately 3.14) 200mm2 = radius2 Taking the square root of 200, 14.14mm is the radius. The diameter is twice the radius, so the diameter is 28.28mm.
