You take the radius (or diameter). If radius you times it by two (since it is half of the Diameter) then times the answer by 3.14. If diameter, times the diameter by 3.14. then round the decimals.
You need to know diameter of each circle, which are different for each circle; each circle circumference is pi x diameter where pi = 3.14159
The radius of the circle is 7.
For any circle in a plane, the ratio of circumference to diameter is a number called pi, approximately 3.14.
Using the Circumference And Area.
It means drawing a circle around a polygon in such that each vertex of the polygon is on the circumference of the circle.
The circumference of a circle with radius of 7 km is 44.0 km (to the nearest tenth), and the area of a circle with radius of 7 km is 153.9 km (to the nearest tenth).C = 2 pi RA = pi R2
For circumference, multiply the diameter by pi and round the product to the second decimal place. For area, multiply the square of the radius by pi and round the product to the second decimal place.
You need to know diameter of each circle, which are different for each circle; each circle circumference is pi x diameter where pi = 3.14159
The radius of the circle is 7.
The radius of a circle is a straight line from the centre of the circle to its circumference.
The radius of a circle is the distance from the circle's centre to its circumference
Each circle with a different radius (or diameter or circumference) is a different size circle.
Round 45,621 to the nearest place given. To the nearest ten
For any circle in a plane, the ratio of circumference to diameter is a number called pi, approximately 3.14.
A cone does not have an intrinsic number. It does have a radius, a circumference a vertical height a slant height an apex angle a proportion of a circle an area of base an area for the slanted face a volume. Each of these has a number associated with it. You will have to decide which one you want!
