Acylinder shaped water tank has a diameter of 8 m and a height of 20 m. what volume of water does the tank contain when it is 60% full? use 3.14 to approximate pi. enter your answer as a decimal to the hundredths place in the box. m³

V = PI x r^2 x H

V = 3.14 x 4^2 x 20 = 1004.8 cubic meters

1004.8 x 0.60 = 602.88 cubic meters

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.
