Area of the circle: pi*11^2 = 121*pi square units

Area of the circle: pi*11^2 = 121*pi square units

Entire surface area: (2*pi*121)+(22*pi*23) = = 748*pi square inches

Using 3.14 as Pi the area of circle is: 379.94

There are two ends, each of area {pi}r2 and the side which can be worked out by cutting the cylinder down (from end to end) and unrolling; one length is the cylinder height (h), the other is the circumference of the end (2{pi}r), giving 2{pi}rh. Area = 2x({pi}r2) + 2{pi}rh Area ~= 2x3.14x112 + 2x3.14x11x11 Area ~= 1520.5in2

Entire surface area: (2*pi*121)+(22*pi*23) = = 748*pi square inches

Using 3.14 as Pi the area of circle is: 379.94

Area = pi*radius squared 11 in = pi*r^2 divide both sides by pi 3.50 in = r^2 take square root of each side 1.9 inches = radius

Total surface area = (2*pi*112)+(pi*22*11) = 1520.531 square inches rounded to 3 decimal places

Radius, r = diameter / 2 Then circumference = 2*pi*r and area = pi*r*r

Surface area of a sphere = 4*pi*radius2 Surface area = 4*pi*112 = 1520.530844 square units.

Total surface area = (2*pi*112)+(22*pi*19) = 660*pi square inches
