What is the radius of a tank that holds 785 cubic feet of oil and is 10 feet tall

The answer to your question is r = 5 ft

Step-by-step explanation:

Data

Volume = V = 785 ft³

height = h = 10 ft

radius = r = ?

pi = 3.14

Formula

Volume of a cylinder = πr²h

-Substitution

         785 = (3.14)r²(10)

-Solve for r²

         r² = 785 / (3.14)(10)

-Simplification

         r² = 785 / 31.4

         r² = 25

-Result

         r = 5 ft

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!
