A whole circle is 360 degrees. So add up the known degrees (115+105+60)=280degrees
Then 360-280=80 degrees
Answer:
98pi
Step-by-step explanation:
Area of circle: pi(r)^2
A1=pi(7)^2
A2=pi(7)^2
A2+A1=98pi
Answer:
B
Step-by-step explanation:
Because it has to be less than or no more than $100
Answer:
Part 1 - A
Answer: 301.592895 m^3
Step-by-step explanation:
The formula for the volume of a cone is calculated the formula:
<u>V = πr^2h/3 </u>
In the question, we are given the value of the radius and height in meters through which we can calculate the volume.
r = 6
h = 8
and we know the value of π to be 22/7, or 3.14285714286.
By substituting these values in the formula, we can solve for volume of the cone:
V = π (6)^2 8 / 3
Volume = 301.592895 m^3
Hope this helps!
