zhannawk [14.2K]

To solve this problem, we simply use the equation of volume for hollow cylinders:

V = π h (R^2 – r^2)

where V is volume, h is height = 10, R is outer radius = 8.4/2 = 4.2, r is inner radius = 6/2 = 3

 

V = π (10) (4.2^2 – 3^2)

<span>V = 86.4π = 271.43 mm^3</span>

Apples cost $0.75 per pound and bananas cost $1.05 per pound
LuckyWell [14K]

Answer:

<em>The baker bought 8 apples and 4 bananas</em>

Step-by-step explanation:

<u>System of Equations</u>

Let's call:

a = pounds of apples

b = pounds of bananas

The baker bought a total of 12 pounds of apples and bananas, thus:

a + b = 12      [1]

Apple cost $0.75 per pound and each pound of bananas cost $1.05 per pound. Thus the total cost is 0.75a + 1.05b. We know he spent a total of $10.20, thus

0.75a + 1.05b = 10.20     [2]

Solving [1] for a:

a = 12 - b       [3]

Substituting in [2]:

0.75(12 - b) + 1.05b = 10.20

Operating

9 - 0.75b + 1.05b = 10.20

Simplifying:

0.30b = 10.20 - 9 = 1.20

Dividing by 0.30:

b = 1.20/0.30

b = 4

From [3]:

a = 12 - 4 = 8

a = 8

The baker bought 8 apples and 4 bananas
