How do you find dimensions of a cylinder with just the volume?

Answers

Answer:Since the volume of a cylinder formula involves the radius, you can solve for the radius and double it to find the diameter.

Write the formula. Volume=π⋅radius2⋅height.

Substitute the dimensions of the shape into the formula. Use 3.14 as the value for π. 791.28=3.14⋅r2⋅28.

Solve the equation for the variable.

Answers

Answer:

i think is 18.6 I not sure

It will be +18.6
Because (-20.4) is a negative number
Imagine a number line you would need 20.4 to get back to 0 since you will start at negative 20.4
39-20.4 is 18.6
So you have 18.6 left which will be on the positive side so that’s the answer

Write an equation of the line that has a slope of 5 and goes through the point (3,3)

Answers

Answer:

y=5x-12

Step-by-step explanation:

The general equation of a line is y=mx+b.

The equation you currently have is y=5x+b.

Plug in the point (3,3) which will get you 3=5(3)+b.

Solve the equation by solving what the y-intercept (b) is to create the new final equation.

3=5(3)+b

3=15+b

b=3-15

b=-12

y=5x-12

(A)The sample space is 1,2,3,4,5,6. Option A is correct

(B) P(rolling a 1) =1/6, Option B is correct

(C)P(rolling a 2)=1/6, therefore option C is incorrect.

(D)P(rolling a 6)=1/6, Option D is correct

(E)In an experimental trial, the outcome must be members of the sample space. Therefore, the outcomes in option (E), 2, 2, 2, 5, 3, 2, 6, 5, 6, 1 are valid.
