The area of a circle is: pi times radius squared
Area of the circle: pi*11^2 = 121*pi square units
Area of the circle: pi*11^2 = 121*pi square units
The area of a circle is calculated using the formula ( A = \pi r^2 ), where ( r ) is the radius. For a circle with a radius of 11 miles, the area is ( A = \pi (11)^2 = 121\pi ) square miles. Using ( \pi \approx 3.14159 ), the exact area is ( 121\pi ) square miles, or approximately 380.132 square miles when calculated numerically.
Entire surface area: (2*pi*121)+(22*pi*23) = = 748*pi square inches
The surface area ( A ) of a right cylinder can be calculated using the formula ( A = 2\pi r(h + r) ), where ( r ) is the radius and ( h ) is the height. For a cylinder with a radius of 4 and a height of 11, the surface area is ( A = 2\pi(4)(11 + 4) = 2\pi(4)(15) = 120\pi ). Hence, the surface area is approximately ( 376.99 ) square units when ( \pi ) is approximated as ( 3.14 ).

Diameter = 11 inches so area = pi*d2/4 = 95.03 sq inches.Diameter = 11 inches so area = pi*d2/4 = 95.03 sq inches.Diameter = 11 inches so area = pi*d2/4 = 95.03 sq inches.Diameter = 11 inches so area = pi*d2/4 = 95.03 sq inches.
measure of central angle/360 degrees = area of sector/area of circle 110 degrees/360 degrees = 40 unit2/ pi r2 unit2 11/36 = 40/pi r2 11 pi r2 = 40 x 36 11 pi r2 = 1,440 r2 = 1,440/11 pi r = square root of 1,440/11 pi r = 20.3 unit approximately
Entire surface area: (2*pi*121)+(22*pi*23) = = 748*pi square inches
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
The general eq'n for a circles area is A = pi r^(2) Hence With a diamter of 22 inches . the radius(r) is half the diameter at 11 inches. Substituting A = pi 11^(2) A = 121 pi Using pi = 3.14 Hence A = 121 X 3.14 A = 379.94 sq.ins. (NOT ins^(2))
Surface area of a sphere = 4*pi*radius2 Surface area = 4*pi*112 = 1520.530844 square units.
