John has a cylindrical water tank in his house with a 4 m radius and 15 m height. The cost of filling the water in the tank is $0.5 per cubic meter. What would be the cost of filling the complete tank? (Use pi = 3.14)

$377

Step-by-step explanation:

Volume of a cylinder is;

V = πr²h

Where;

r is radius

h is height

We are given;

radius; r = 4 m

Height; h = 15 m

Thus;

V = π × 4² × 15

V = 753.9822 m³

Cost of filling the tank is $0.5 per m³.

Thus, total cost to fill this tank is;

C = 0.5 × 753.9822

C = 376.9911

C ≈ $377

step-by-step explanation:

a cube has 6 sides

the probability of getting 5 on the first cube is 1/6 since only one side of the cube has 5 on it.

there are 3 sides of the cube with even number on it [2,4,6]

therefore the probability of getting even number is 3/6

for both events to happen together, the probability would be

1/6 x 3/6 = 12/36

which simplifies to 1/12

add the numbers under frequency to find the total number:

5 + 8 +7 + 4 + 0 +1 = 25

the answer is 25.
