The two equations you must know to solve this are
The circumstance of a circle is the value of pi times the diameter
c=pi*d
-and-
The radius of a circle is halve the diameter
r=.5d or d=2r
If we plug in 62.8 for c, 2r for d and 3.14 for pi, the equation becomes
62.8=3.14*2r
Divide by 3.14
20=2r
Divide by 2
10=r
the radius is ten meters
circumference (C) = 2piR = Two x Pi x Radius Pi = 3.14.... R= C/2pi if C = 628 R = 628/ 2 (3.14...) R= 99.949 cm
Using pi as 3.14 it works out that the diameter is 20 cm
circumference (C) = 2piR = Two x Pi x Radius Pi = 3.14.... R= C/2pi if C = 628 R = 628/ 2 (3.14...) R= 99.949 cm
200*pi feet, or approximately 628 feet. The formula for the circumference of a circle is C = 2*pi*r.
14.139
Since the circumference of a circle is found by: C = 2 X Pi X r , where Pi can be rounded to 3.14 C = 2 x 3.14 x 100 C = 628 m The circumference can also be found by using the diameter: C = Pi X d, where d = 2r
Area = p* r2 628 ft2 = pi*r2 divide both sides by pi, which is the coefficient of r2 199.8986 = r2 Take square root each side 14.1 feet = radius =============
The height of a cylinder with lateral area of 628 and radius 2.5 is approximately 39.98 units.
If I understand the question correctly, it is seeking the proportion of 628 cm in 3.75 metres. 628 cm/3.75 m = 628 cm/375 cm = 1.674666...
2060 feet and 4 inches
6280 i think Im not sure for sure though
39.25 cubic cm (628 DIVIDED BY 8 DIVIDED BY 2
1% of 628 = 1% * 628 = 0.01 * 628 = 6.28
Using pi as 3.14 it works out that the diameter is 20 cm
