Use the pythagorean theorem if you cannot directly measure it. a squared plus b squared = c squared
Answer:
A. (-1, -16)
Step-by-step explanation:
The formula in computing the circumference of a circle is:
<span>C = 2πr</span>
Where:
r = the radius of the circle
Substituting
the given measurement of radius to the formula:
C
= 2 (π) (7 feet)
C
= 14π feet
Therefore,
the circumference of the circle is 14π ft.
Answer:
Option B. 93.46 ft³
Step-by-step explanation:
In the given question tow solids are given.
Their heights are same and the cross sectional areas at every level parallel to the respective bases are same which means total volume of solids are also same.
We have to find the volume of the cone.
We know the formula of volume of a pyramid 
Now area of the base = area of a right angle triangle = 
Here height of the right angle triangle = 8 ft
and base of the triangle = 
Now area of base = 
Now volume of cone = volume of pyramid = 
Therefore Option B. is the answer.
Answer:
a=1
Step-by-step explanation:
This is assuming that by A you mean y=ax+b. So you have y=x-31, following the y=ax+b equation, A is the coefficient in front of x, which is 1.
