Step-by-step explanation:
Given
Radius (r) = 4 inches
height (h) = 11 inches
Total surface area of cylindrical oil can is
= 2πr ( r + h)
= 2 * 22 / 7 * 4 ( 4 + 11)
= 2 * 22/7 * 4 * 15
= 377.14 inches ²
Answer:
m= 
Step-by-step explanation:
use this formula if you're having two points or a graph
Hello!
Question 1
We first have to convert everything to yards since the concrete is charged by the cubic yards
15 feet = 5 yards
15 feet = 5 yards
3 inches = 0.08333
Multiply these to find the volume
5 * 5 * 0.08333 = 2.08325
Multiply this by the cost
2.08325 * 46 = 95.83
The answer is C) $95.83
------------------------------------------------------------------------------------------------------
Question 2
You have to find the volume of the first pyramid
The equation we use is

V is volume
l is length
w is width
h is height
Put in the values we know

Multiply

Divide
V = 2389.3333
Now we use this to find the side length of the second pyramid

Multiply both sides by 3
<span>7167.999 = lw * 112
</span>
Divide both sides by 112
63.9999 = lw
Since it is a square pyramid we know that sides are equal
63.999 = l^2
Take the square root of both sides
8 = l
The answer is B) 8in
Hope this helps!
since parallel lines have the same slope, If the slope of AB is -3 then the slope of CD will also be -3
