You have answered this question for yourself; the answer is '10'
Do you mean to ask ; What is the circumference/area of a circle, with a diameter of '10'?.
If so , commit to memory ' elementary school maths.
A = pi r^2
C = 2 pi r or pi d .
From this 2r = d
Hence 2r = 10
r = 5
C = 10 pi = 31.41592.... units
A = pi 5^2 = 25 pi = 78.5398... units^2
That's easy - 10. Or did you mean circumference or area?
divide by pi which is 3.1415927 and on and on
The radius(radii is the plural) of the circle is half the distance of circle's diameter. The formula is r=(1/2)diameter.
Take the circumference of a circle and divide it by the diameter of that circle: ∏=C/D
in place of r (radius) write d/2 where d is diameter
Area is 4.6 m2
If a circle's diameter is 10, the circumference is: 31.416
Area of the circle = pi*radius2 = pi*52
5,2
Diameter of the circle: 2 times 10 = 20 in
For a circle where sector measures 10 degrees and the diameter of the circle is 12: Sector area = 3.142 square units.
the formula for that is C= d times 3.14 but i will let you do your homework to yourself. No cheating! If the circle has a diameter of 10, the answer would be about 31.4
First find the circumference of the whole circle using Pi x diameter. Halve the answer and add the diameter. Thus: 3.1416 × 10 = 31.416 ÷ 2 + 10 = 25.708cm So the perimeter of the semi-circle is 25.7cm
You double the radius.. if the radius is 10 the diameter is 20.
Circumference = (pi) x (diameter) = 10 pi = 31.416 yards (rounded)
The circumference of circle whose diameter is 10 is: 31.42 (diameter x Pi = circumference).
The area of a circle with a diameter of 10 centimeters is: 78.54 cm2
The circumference of a circle with a 10 millimeter diameter is about 31.42 mm
