Mnenie [13.5K]

The complete question is;

The height and diameter of a cone-shaped storage tank are 9 feet and 14 feet respectively. Find the volume of liquid the tank can hold. Round your answer to the integer, if necessary. Use the approximate of value of π, that is 3.14.

Answer:

Volume = 462 ft³

Step-by-step explanation:

We are given;

Height;h = 9 ft

Diameter;d = 14 ft

So, radius;r = 14/2 = 7 ft

Volume of a cone is given by;

V = ⅓πr²h

Where π = 3.14

Thus;

V = ⅓ × 3.14 × 7² × 9

V = 461.58 ft³

Approximating to nearest integer gives; V ≈ 462 ft³

So assuming that the total =27
r+b=27
r=-5+3b
r=3b-5
subsitute 3b-5 for r in first equation
3b-5+b=27
4b-5=27
add 5
4b=32
divide by 4
b=8
subsitute
b+r=27
8+r=27
subtracct 8
r=19
