Taking pi as 3.14:-
Volume = 4/3*3.14*43 = 267.946666 .... recurring 6 cubic units
The surface area of a sphere is 4(3.14)R2where R is the radius of the sphere so the surface area of your dome is half of that. 2(314)R2
S.A. = 4 pi r^2 Substituting 314 = 43.14r^2 Algebraically rearrange 100/4] r^2 = 314 / (4 * 3.14) r = sqrt[314/(4*3.14)] r = sqrt[ 100/4] r = sqrt[25] r = 5 inches The circumference of a sphere is a circle. Hence C = 2 pi r C = 23.145 C = 10*3.14 C = 31.4 inches.
divide the circumference by pie (3.14) and the answer would be the radius. for example circumference = 314 pie = 3.14 so 314 divide by 3.14 = 100 so the radius = 100

It is: 4*pi*52 = 314.159 square cm to three decimal places
divide the circumference by pie (3.14) and the answer would be the radius. for example circumference = 314 pie = 3.14 so 314 divide by 3.14 = 100 so the radius = 100

314 sqmm
Approximatly 50inches
Divide 314 by pi and square root the answer which will give you the radius.
Using 3.14 as Pi the area of circle is: 314.0
The area is 314 cm2
