Set up the equation and solve using the formula for area of a circle: (pi = 3.14)
a = P * r-squared (substitute with known numbers)
113.04 = 3.14 * r-squared (divide both sides by pi (3.14))
36 = r-squared (find the square root of 36 to solve for the radius)
6 = r
The surface area of a 10 cm dish can be calculated using the formula for the surface area of a sphere, which is 4r2. Plugging in the radius of the dish (5 cm), the surface area would be 314.16 square centimeters.
The scientific name of radius is "radius." Radius is one of the two long bones in the forearm, located on the lateral side of the arm when in the standard anatomical position.
area of object = (1/3) pi * radius^2 = (1/3) (pi) * (0.6)^2 = 0.377 Find the diameter of this object (assuming it's a circle), and that's the answer: diameter = radius * 2 radius = square root (area / pi) diameter = 2 * square root (area / pi) diameter = 2 * (0.335) = 0.67
The surface area of a 100mm dish can be calculated using the formula for the surface area of a sphere, which is 4r2. Since the dish is a hemisphere, the formula becomes 2r2. Plugging in the radius of 50mm (half of 100mm), the surface area of the dish is approximately 15,708 square millimeters.
The surface area of a 15cm plate can be calculated using the formula for the surface area of a circle, which is A r2. Since the plate is circular, the radius (r) would be half of the diameter, which is 15cm. Therefore, the surface area would be A (7.5)2 176.71 square centimeters.
Assuming the satellite is spherical, the radius is half the diameter, which is 30 cm. The surface area of a sphere is 4 pi times the radius squared. 4 * 3.14 * 30 ^ 2 = 12.56 * 900 = 11304 square cm
Archimedes proved that the area enclosed by a circle is equal to that of a triangle whose base has the length of the circle's circumference and whose height equals the circle's radius. Circle area therefore comes to π(pi) multiplied by the radius squared.area = (pi) * (60)2 which is the same as 3.14 * 3600 = 11304 square feet.

The area increases as the square of the radius (or diameter). So if you double the radius you * 4 (quadruple) the area. Treble the radius, you *9 the area.
The area of a semicircle is half of the area of a circle. The area of a circle is pi x radius x radius. So the area of a semicircle is 1/2 x pi x radius x radius or (pi x radius x radius) / 2.
The area increases as the square of the radius (or diameter). So if you double the radius you * 4 (quadruple) the area. Treble the radius, you *9 the area.
Area = π × radius² → radius² = area/π → radius = √(area/π) Circumference = 2 × π × radius = 2 × π × √(area/π) = √(2² × π² × area/π) = √(4 × π × area)
Area = pi * (radius^2) Where (radius^2) is radius squared, or radius to the second power. do some algebraic steps: Area / pi = radius^2 radius^2 = Area / pi square root (radius^2) = square root (Area / pi) radius = (plus or minus) square root (Area / pi) If you are not working with imaginary numbers then radius = square root (Area / pi)
If you triple the radius of a circle, the area will increase by 9. Area is proportional to the square of the radius.
When you try to figure out an area of a circle, you square the radius, then multiply it by pi to get the area of a circle. A radius square is radius x radius, or radius squared.
A= Area of the circle¶= Pi (About 3.14)r= Radius squared (Radius times radius)3.14 * Radius squared
Area = (pi) x (Radius)2 (Radius)2 = Area/pi Radius = sqrt(Area/pi) Diameter = 2 x radius = 2 x sqrt(Area/pi)
