If a plant manufacturing carpet backing has a cylindrical tank that is 3 meters high and is 6 meters in diameter what is the volume of the tank Assume 3.14 for pi. A)28.3 m3 B)37.7 m3 C)56.5 m3 D)84.8?
radius = diameter ÷ 2 volume cylinder = area of end × height → volume = π × radius² × height → volume = π × (diameter ÷ 2)² × height →volume = π × (6m ÷ 2)² × 3 m → volume = 27π m³ ≈ 27 × 3.14 m³ = 84.78 m³ ≈ 84.8 m³ to 1 dp.
What is the volume of a sphere whose surface area is 36 pi square meters?
surface area = 4πr² → r = √(A/4π) = √(36π m²/4π) = √(9 m²) = 3 m volume = (4/3)πr³ = (4/3)π(3 m)³ = (4/3)π27 m³ = 36π m³
How many cylindrical cans of diameter 12 cm and height 15 cm can be filled from a 3 m by 2 m by 1.5 m rectangular tank?
Volume of each can = (pi) R2 H = (pi) (6)2 (15) = 540 pi cm3Volume of the tank = 3 x 2 x 1.5 = 9 m3 = 9 x 106 cm3IF the tank is full when you begin, and you don't spill any, then you can fill9 x 106 / 540 pi = 5,305 cans, with 279.5 cm3 (0.165 can) left over.
What is the volume of a sphere with radius of 2 m?
Volume of a sphere is 4/3 pi times the cube of its radius.
What the density of a substance that has a volume 15ml and a mass 60g?
15ml is the same as 15 cubic centimeters. D = M/V so the answer is 60g/15cc which equals 4 grams/cm cubed.
