Jason wants to fill a cylindrical water tank to its full capacity. he knows that the volume of the tank is equal to the product of pie, the square of the radius of the tank, and the height of the tank. jason measured the height of the tank and found it to be 15 feet. he also measured the radius of the cylindrical tank and found it to be 10 feet. if v represents the volume of the cylindrical tank, then which of the following equations can be used to calculate the volume of the tank?

The volume of tank is calculated by the equation .

Step-by-step explanation:

It is given that the height of the cylindrical tank is 15 feet and the radius of the cylindrical tank is 10 feet.

The formula to find the volume of cylinder is

Therefore the  volume of tank is calculated by the equation and the volume of tank is 4712.39 feet³.

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it

hello,

b) 62.47% of the students are between 14 and 18 years old.

step-by-step explanation:

mean = 15 and standard deviation = 2

student between 14 to 18

formula used z-score

for age 14 , z score

using z-table , p(z> -0.5)=0.3085

for age 18 , z score

using z-table , p(z< 1.5)=0.9332

p(-0.5< z< 1.5)=0.9332-0.3085 = 0.6247

thus, 62.47% of the students are between 14 and 18 years old.
