3 mathematical formulas including pi?
Area of a circle: pi*radius^2 Circumference of a circle: 2*pi*radius or diameter*pi Surface area of a sphere: 4*pi*radius^2
What is the radius of a circle if the surface area is 2500 square centimeters?
To find the radius of a circle when given the surface area, you can use the formula for the area of a circle: A = πr^2, where A is the surface area and r is the radius. Given that the surface area is 2500 square centimeters, you can plug this value into the formula and solve for the radius. 2500 = πr^2 r^2 = 2500/π r ≈ √(2500/π) r ≈ √(795.77) r ≈ 28.2 cm Therefore, the radius of the circle is approximately 28.2 centimeters.
How does the dimensions of a cylinder help you to find its surface area?
Total Surface Area of Cylinder = 2 x pi x radius x (radius + height)Surface area of base circle = pi x radius x radiusSurface area of curved part = 2 x pi x radius x heightHence, total surface area = (2 x area of base circle) + (area of curved part)= (2 x pi x radius x radius) + (2 x pi x radius x height)= 2 x pi x radius x (radius + height)
How do you get a area from the diameter?
The equation for the surface area of a circle is Pi times the radius squared. Pi x r^2 = Area of a circle The radius is 1/2 the diameter therefore if d is the diameter; Pi x (d/2)^2 = Area of a circle

What is the surface area of an 18' circle?
The surface area of a circle is calculated using the formula ( A = \pi r^2 ), where ( r ) is the radius. For an 18-foot circle, the radius is 9 feet (half of 18 feet). Plugging this into the formula, the surface area is ( A = \pi (9)^2 ), which equals approximately 254.47 square feet.
What is the formula of the surface area of a circle?
The area of a circle is pie(22/7) or (3.14) times R2 R = the radius of the circle (1/2 of the diameter)
How do you calculate the surface area of a circle with a radius of 4?
A=pi * r^2, so 16pi
Formula and result of area of circle?
The formula for the area of a circle is: Area = (pi) x (Radius)2 . When you know the radius of the circle and you use it to calculate the area of the circle, the result will be equal to (pi) x (Radius)2 .
Is the area of a circle of radius 14 units equal to the surface area of a sphere of radius 7 units?
surface_area_sphere = 4 × π × radius_sphere² = π × (2 × radius_sphere)² area_circle = π × radius_circle² These are equal when: π × radius_circle² = π × (2 × radius_sphere)² → radius_circle² = (2 × radius_sphere)² → radius_circle = 2 × radius_sphere As the given circle has a radius of 14 units and the given sphere has a radius of 7 units, and 14 = 2 × 7, it is true that the area of a circle with a radius of 14 units is the same as the surface area of a sphere with a radius of 7 units.
