✰ Question Given :

• ➦ Determine the surface area of a sphere having a radius of 7 cm ?

✰ Required Solution :

★ Value Given to us :

• ➸ Radius of Sphere = 7 cm

★ Formula Used Here :

• ➲ Surface Area of Sphere = 4πr²

★ Putting Value in Formula :

• ➸ Surface area = 4 × 22 / 7 × (7) ²cm

• ➸ Surface area = 4 × 22 × 7 cm

• ➸ Surface area = 88 × 7 cm

• ➸ Surface area = 616cm²

✰ Therefore :

• ➦ The surface area of a sphere having a radius of 7 cm will be 616cm²
