Question

the surface area of sphere of radius 14 centimetre is.(1) 1386cm suquare (2) 2464cm suquare(3) 1400 cm suquare (4) 2000 cm suquare​

Answer 1

Answer:

your answer is (2) 2464 cm²

Step-by-step explanation:

surface area of the sphere = 4πr²

given that = r = 14 cm

so,

   = 4 x 22/7 x 14 x 14

   = 4 x 22 x 2 x 14

   = 2464 cm²

correct option is (2) 2464 cm²

Answer 2

Step-by-step explanation:

radius = 14 cm

value of pie = 22/7 or 3.14

Total Surface Area Of Sphere = 4 × pie × (square of radius)

= 4 × 22/7 × (14×14)

= 4 × 22 × 2 × 14

= 88 × 28

= 2464 cm square

Therefore , the surface area of sphere of radius 14 cm is 2464 cm square.
