find volume and surface area of sphere with radius 4.2cm
Answers
Volume of a sphere = 310.464 cm³ & Surface Area of a Sphere = 221.76 cm² if Radius = 4.2 cm
Step-by-step explanation:
Volume of a sphere = (4/3) π R³
Surface Area of a Sphere = 4 π R²
R = 4.2 cm
π = 22/7
Volume of a sphere = (4/3) (22/7) 4.2³
= 310.464 cm³
Surface Area of a Sphere = 4 (22/7) 4.2²
= 221.76 cm²

Volume of Sphere:
Formula= 4/3 π R³
putting in values,
Volume = V = (4/3) * (22/7) * (4.2)³ = 310.46 cm³
Area of Sphere:
Formula = 4 π R²
Area= A = 4(22/7)(4.2)³ = 221.7 cm²
