Answer:

C. Sphere

Volume:

  • V = 4/3Ï€r³ = 4/3*9³π = 972Ï€ cm³

Surface area:

  • A = 4Ï€r² = 4*9²π = 324Ï€ cm²

B. Cylinder

Volume:

  • V = Ï€r²h = 3²*9Ï€ = 81Ï€ in³

Surface area:

  • A=2Ï€rh + 2Ï€r² = 2Ï€(3*9+3²) = 2Ï€(36) = 72Ï€ in²

A. Right Cone

Volume:

  • V = 1/3Ï€r²h = 1/3Ï€*5²*21 = 175Ï€ cm³

Surface area:

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