The diameter is a straight line from one side os the circle, through the centre point, to the opposite side of the circle.
The radius is a straight line from one side of the circle to the centre point only.
So Two radii add to make one diameter.
Hence algebrauically,
d = 2r
If d = 0.75
Then
r = 0.75/ 2
r = 0.375
75
Circumference of a circle = 2*pi*radius or diameter*pi
.75 inches or 19 Millimeters is the diameter so the radius is .375 inches or 9.5 Millimeters.
l= rθ Here θ = 75 * π/180 (Converting degrees into radian) r= l/θ = 75/ 75/180 π = 180/π = 57.3 approximately.

to get the radius of a circle given the diameter, than simply divide the diameter by 2 to get the radius. in this case, the answer to your question would be 37.5 cm. hope this helps!!!
radius = square root of (75/pi) = 4.886025119 diameter = 2*radius = 9.772050238 or 10 mm to the nearest integer
75 rounded
The radius of a circle is half of its diameter. If the diameter of the circle is 150 cm, then the radius would be half of that, which is 75 cm. The radius is the distance from the center of the circle to any point on its circumference.
The area of a circle with a diameter of 75 inches is: 4,418 square inches.
Circumference of a circle = 2*pi*radius or diameter*pi
If the circumference of a circle is 75 inches, the diameter is: about 23.87 inches. (diameter = circumference divided by pi).
If the circumference of a circle is 75 feet, the diameter will be 23.87 feet. (d = c divided by Pi).
11.93662073 inches
A circle with a radius of 75 feet has an area of 17671.458676442588 square feet. You calculate this by using the area of a circle formula, which is A=pi*r^2.
Area of a circle = pi times radius squared
