Find the surface area (in cm2) of a sphere of diameter 28 cm.
Show answer & explanation
Correct answer: D
Explanation
The correct answer is Option 4 i.e. 2464.
Given that
Diameter = 28 cm
Hence radius = 14 cm
Formula used
Surface area of a sphere = 4πr2
Substituting the values we get
Surface area = 4π × 14 × 14 = 2464 cm2
