7 inches.
Radius: 35/2 = 17.5cm
If 35 is the radius, then its 70.
That depends on what is meant by a 35 foot circle but the area of a circle is pi times radius squared
The radius of a circle with an area of 35 mm squared is 3.34mm
A circle with a radius of 35 feet has an area of 3,848.45 square feet.
Area of a Circle (A) = pi times the radius (r) squared A = (pi) (r)2 Diameter of a Circle (d) = 2 times the radius (r) d = 2r First, find the r Since the diameter (d) = 70 cm, then 70 cm = 2 r (70 cm)/2 = r r = 35 cm Now that you have found the value of the radius (r), you can plug in r for the equation for the area (A) of a circle: A = (pi) (35 cm)2 A = (pi) 1225 cm2 At this point you can multiply 1225 cm2 by pi with a calculator to get the value of 3848.45100065 which can be simplified to 3848.5 cm2
Area of a circle = pi*radius squared
The circumference of a circle that has a diameter of 35 inches is 109.96 inches.
The radius of a circle with an area of 35 square inches is 3.34 inches.
The diameter of a circle when the circumference is 35 cm is: 11.14 cm (circumference divided by Pi = diameter).
radius = 35/(2*pi) in cm
(Note: for typing purposes, pi will be represented as n) The formula for circumference is 2nr. First we need to find 'r' which stands for radius (the straight distance from the centre of the circle to the edge). Since the radius is half of the diameter, the radius is 70/2=35 yds. Now we can put 35 yds into the formula: 2*n*35 = 219.91 yds (rounded to 2 decimal places).
