Question

If the radius of sphere 7m then surface area is .
(a) 616m2 (b) 216m2 (c) 105m2 (d) 112m2.​

Answer 1

Here the radius of the sphere is given to be 7 m

We have to find the surface area of the sphere

Surface area of the sphere = 4πr²

                                            = 4 × (22/7) × 7²

                                            = 4 × 22 × 7

                                          = 616 m²

So, the surface area of the sphere will be 616 m²

Hence, option a will be the correct answer

Answer 2

Step-by-step explanation:

the surface area =4πr²

4×22/7×7²

4×22×7=616m²
