98 cm^2
The radius is 7cm
3.5 cm
circumference of a circle = 2*pi*radius or diameter*pi
A cone with a slant height of 22cm and radius of 7cm has a total surface area of about 637.74cm2
The circumference of a circle with a 7cm radius is 44cm. The area is 154cm2
153.94 square cm
Area of the circle: pi*7squared = 153.93804 square cm
98 cm^2
7cm; the diameter of a circle is twice its radius.
The radius is 7cm
The formula for the surface area of a sphere is 4πr^2, where r is the radius of the sphere. Plugging in the radius of 7cm, we get 4π(7)^2 = 4π(49) = 196π. Therefore, the surface area of a sphere with a radius of 7cm is 196π square centimeters.
