If you mean a circle, use the formula for the area of a circle: A = pi x r2.
The circumference is 565.5 feet. The area is 25,450 square feet. The diameter is 180 feet.
The radius is 12
Find the area of the shaded sector. radius of 3 ...A+ = 7.07
To find the area of a square, you multiply the length by the width. In this case, 90 ft x 90 ft equals 8100 square feet. This is because each side of the square is 90 feet long, so the total area covered by the square is 8100 square feet.
90 square meters is about 968.7519 square feet.
The radius is 8 feet.
The circumference is 565.5 feet. The area is 25,450 square feet. The diameter is 180 feet.
The surface area of a sphere is (4 pi) x (radius of the sphere)-squared.We're not completely sure of what a "90' sphere" is. If you're saying that thesphere's diameter is 90-ft, then its radius is 45-ft, and its surface area is(4 pi) x (45-ft)-squared = 25,446.9 square feet, or 2,827.4 square yards. (both rounded)
Using 3.14 as Pi the area of circle is: 6358.500000000001
Area = 90 feet²
To calculate the area of a baseball field, you need to find the area of the infield and outfield separately, and then add them together. The infield is a square with sides measuring 90 feet each, so its area is 90 feet multiplied by 90 feet. The outfield is a quarter circle with a radius of around 250-300 feet, so its area can be calculated using the formula for the area of a circle: π times the radius squared. Add the areas of the infield and outfield to get the total area of the baseball field.
area = length x width area = 90 feet 10 feet x 9 feet = 90 square feet.
Well a circle has 360 degrees so a sector of 90 degrees has an area equal to 90/360 (or 1/4) of a circle with the equivalent radius. The area of a circle is defined as PI*Radius^2 so the area of a 90 degree sector will be 1/4*PI*Radius^2. The area will be 1/4*3.14*10^2 or 78.5 in^2.
Area of sector: 38.485 sq ft Area of circle: 153.93804 sq ft Arc in degrees: (38.485/153.93804)*360 = 90.00114592 or about 90 degrees Arc in feet: 10.99557429 or about 11 feet
The question is seriously flawed and so cannot be answered. Volume cannot be measured in cm, nor can surface area be measured in cm. Furthermore, a radius of 90 cm, volume of 200 cubic cm and surface area of 180square cm are inconsistent. No two of them can refer to the same sphere!That is, with the appropriate units,radius = 90 implies volume � 200, surface � 180volume = 200 implies radius � 90, surface � 180surface = 180 implies radius � 90, volume � 200.
Volume = pi R2 Hpi R2 (90) = 28,077R = sqrt [ 28,077/(90 pi) ] = 9.965 feet(rounded)
The radius is 12
