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

Kisachek [45]

Answer:

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

Using the graph to the right, write the ratio in simplest form. BD/AD

Romashka [77]

Answer:

$\frac{BD}{AD} = \frac{5}{7}$

Step-by-step explanation:

Coordinate of B = 1

Coordinate of D = 6

Coordinate of A = -1

AD = |-1 - 6| = |-7| = 7 units

$\frac{BD}{AD}$

Plug in the values

$\frac{BD}{AD} = \frac{5}{7}$
