What is the volume of the cylinder?Base circumference : 88 cm; height: 12 cm
Step 01 : Compute radius from base circumference
What is the volume of the cylinder?Base circumference : 88 cm; height: 12 cm
Base circumference = 2πr = 88 cm
Step 01 : Compute radius from base circumference
What is the volume of the cylinder?Base circumference : 88 cm; height: 12 cm
Base circumference = 2πr = 88 cm
Step 01 : Compute radius from base circumference
i.e., 2 ×227× r = 88 cm
What is the volume of the cylinder?Base circumference : 88 cm; height: 12 cm
Base circumference = 2πr = 88 cm
Step 01 : Compute radius from base circumference
i.e., 2 ×227× r = 88 cm Or r =
88 × 72 ×22 = 14 cm
What is the volume of the cylinder?Base circumference : 88 cm; height: 12 cm
Base circumference = 2πr = 88 cm
Step 01 : Compute radius from base circumference
i.e., 2 ×227× r = 88 cm Or r =
88 × 72 ×22 = 14 cm
Step 02 : Compute volume. r = 14 cm and h = 12 cm
Volume of cylinder = πr2h
