Answer:
area of semicircle only = 113.43 mm²
total area = 185.43 mm²
Step-by-step explanation:
(8.5²)(π)(0.5) = 113.43 mm²
(12)(12)(.5) = 72 mm²
72 + 113.43 = 185.43 mm²
Answer:

Step-by-step explanation:
We know that the line has a slope of 2 and it passes through the point (3, -4).
So, we can use the point-slope form:

Where m is the slope and (x₁, y₁) is a point.
So, let’s substitute 2 for m and (3, -4) for (x₁, y₁). This yields:

Solve for y. Distribute the right:

Subtract 4 from both sides. Therefore, our equation is:

Probability sampling simply illustrates a scenario where the subjects of the population have an equal opportunity.
<h3>What is probability sampling?</h3>
Probability simply means the likelihood of the occurence of an event.
In this case, in probability sampling, the subjects of the population have an equal opportunity.
In non-sampling, an equal opportunity isn't given.

Answer:
8835.73ft^3
Step-by-step explanation:
First:
Find area of the base circle.
Diameter is 15, so radius is 7.5
Area of the base circle is 56.25pi (use formula: A=pi(r)^2 ) (also ill convert pi into decimals only later)
next find the volume of the cylinder
height is 40 so volume = 56.25pi*40 = 2250pi
next find the volume of the dome at the top.
you know the radius is 7.5
Use volume of sphere formula below :
4
/3πr^3
=1767.15
alright now add the two bolded values
1767.15+2250pi
= 8835.73
hope this helps
