The formula in getting the surface area of a cylinder is 2 pi r2 + 2 pi r h
SAC = (2)(3.14)(7)2 + (2)(3.14)(7)(25)
= (2)(3.14)(49) + (2)(3.14)(7)(25)
= (6.28)(49) + (6.28)(175)
= 307.72 + 1099
SAC = 1406.72 cm3
The general formula, given radius r and height h, for the volume V of a cylinder is:V = (pi)r2h. In this instance, (pi)(252)(145) = 2.8 X 105 cubic centimeters, to the justified number of significant digits (limited by "25").
It is 25cm
A cube with a face diagonal of 25cm has a surface area of 1875cm2
The area of a sphere is Area = 4(pie)r^2 If this is a cylinrical tank with spherical ends you need the length. The area of the cylinder part is (pie)r^2 x length then add to area of sphere
height: 25cm width: 19cm
A rectangle or perhaps a parallelogram
Since the diameter is 10cm, the radius is 5cm. The area of the base is 25*pi square cm. We must multiply that base value by the height, which makes 625pi cubic cm.
to find the circumfrence you do pi times diameter ( 50* approx 3.14) which gives you 157cm
25cm x 25cm = 625cm
25cm = 250mm
25cm = quarter metre.
25cm is longer than 200mm which equals 20cm
