Question 30 Answer and Explanation _ACT June 2020 Form C02 Math Section

30. A formula for the volume, V, of a right circular cylinder is $V=\pi{r}^{2}h$ , where r is the radius and h is the height. The cylindrical tank shown below has radius 6 meters and height 5 meters and is filled with water.

Given that the weight of 1 cubic meter of water is approximately 2,205 pounds, the weight, in pounds, of the water in the tank is:

F. less than 400,000.

G. between 400,000 and 900,000.

H. between 900,000 and 1,200,000.

J. between 1,200,000 and 1,700,000.

K. more than 1,700,000.

Answer and Explanation

Your Answer is

Correct Answer is J

Explanation

Find the volume of the cylinder as: π*62*5≈565 (m3), the weight of 1m3 of water is 2205pounds, so the weight of the entire sink water is 565*2205=1245825, so choose J
