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
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
For a circle where sector measures 10 degrees and the diameter of the circle is 12: Sector area = 3.142 square units.
Diameter of the circle: 2 times 10 = 20 in
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
