Radius is found out by dividing the diameter by 2 . The radius of a circle with a diameter of 55 cm is 27.5 cm
The points ​(minus−1111​,minus−44​) and ​(55​,55​) are the endpoints of the diameter of a circle. Find the length of the radius of the circle.
The area of a circle is calculated as the value pi(3.1416...) times the square of the radius of that circle.In this case, where a circle has a diameter of 55 meters, the radius, which is half the diameter, will be 25 meters.So to solve for the area (A) of this circle:A = pi x r2 = 3.1416 x 25m x 25m = 1963.5m2 = 1963.5 square meters.
what is the area and circumference of a circle with a diameter of 55 centimeters
The circumference of a circle with a diameter of 55 mm is: 172.8 mm
PiR2 (Pi) x (radius) squared 3.14 x (55/2) squared (3.14 x 27.5) x (3.14 x 27.5) = 7456.32 sq. ft.
Area is 9,500 mm2
The circumference of a 55-foot diameter circle is about 172.8 feet. (C = d x Pi)
452.38 feet = circumference1.) Formula for circumference (perimeter) of a circle = 2 x pi x radius OR pi x diameter(because 2 x radius = diameter)2.) Pi = 3.14153.) 2 x 3.1415 x 72 feet = 452.38 feet
It is: 55%
55% is 55 hundredths, 0.06 is 6 hundredths.
Area = pi*r2 Area = pi(4.2)2 = 55 units2 ========
