Answer:

C. Sphere

Volume:

  • V = 4/3πr³ = 4/3*9³π = 972π cm³

Surface area:

  • A = 4πr² = 4*9²π = 324π cm²

B. Cylinder

Volume:

  • V = πr²h = 3²*9π = 81π in³

Surface area:

  • A=2πrh + 2πr² = 2π(3*9+3²) = 2π(36) = 72π in²

A. Right Cone

Volume:

  • V = 1/3πr²h = 1/3π*5²*21 = 175π cm³

Surface area:

  • A=πr(r+√(h²+r²)) = 5π(5 + √(21²+5²)) = 5(26.58)π ≈ 133π cm²
