What is the volume of a sphere that has a surface area of 49pi square cm?
Well, darling, the surface area of a sphere is given by the formula 4πr², where r is the radius. So, if the surface area is 49π, then the radius squared is 49, making the radius 7 cm. Now, the volume of a sphere is (4/3)πr³, so plugging in a radius of 7 cm gives a volume of 179π cubic cm. Voilà!

'What is the surface area of a sphere with a radius of 5 dm?
surface area of a spere=4*pie*r2 when r (radius)=5 pie=22/7 surface area=4*22/7*5*5 =2200/7 =314.2 dm2
What is the volume and surface area of a sphere with a radius of 7 simplified please?
Volume is 4/3 pi*radius*radius*radius 3.14 times 7 times 7 times 7 times 4 divided by 3= volume 1436.2666666 Surface area is 4 * pi * radius * radius 4 times 3.14 times 7 times 7=surface area 615.44
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.
