Answer:
753.6 cubic units
Step-by-step explanation:
A collar of Styrofoam is made to insulate a pipe. Find its volume. The large radius R is to the outer rim. The small radius r is to the edge of the insulation. Use pi ≈ 3.14 r=2 R=4 h=20
The volume of the pipe formula is given as:
Use pi ≈ 3.14 r=2 R=4 h=20
Volume =h × π (R² -r²)
Volume =20 × 3.14 × (4² - 2²) cubic units
Volume = 62.8 × ( 16 - 4) cubic units
= (62.8 × 12 )cubic units
= 753.6 cubic units
