To figure out this problem you need to find the area of the cylinder A= pi r^2 *h
Then find the area of the cone 1/3*pi*r^2 *h
Subtract the two answers
Answer:
7.81*10^11
Step-by-step explanation:
1.86*10^5=186,000
186,000*4,200,000=7.81*10^11
Do you mean 3/√11 ? In this case, you'll have to multiply both, numerator and denominator by the denominator ...
The missing coefficient of the x-term after finding the product of (-x - 5)², is: C. 10.
<h3>What is the Coefficient of a Variable?</h3>
The coefficient of a variable is the numerical value that comes before the variable and multiplies it.
Find the product of (-x - 5)²:
(-x - 5)(-x - 5)
-x(-x - 5) -5(-x - 5)
x² + 5x + 5x + 25
x² + 10x + 25
The x-term is "10x". The coefficient is: 10.

The unit rate in the equation is 20.
Option C) is the correct answer.
<u>Step-by-step explanation</u>:
Step 1 :
In the given equation y = 20x
where,
x ⇒ total number of hours for tutoring
20 ⇒ the cost per hour of tutoring
y ⇒ the total cost for total hours of tutoring
Step 2 :
Unit rate refers to the value per hour.
Here, the cost for 1 hour of tutoring is $20.
∴ The unit rate is $20 per hour of tutoring.
