Finding the Volume of a Rectangular Pyramid
Your overall formula for finding the volume of these multi-faceted shapes is V = (l x w x h) / 3. Basically, your first step is finding the area of the base by multiplying length by width. Once you determine the area of the base, multiply that by the height.
Answer:
D
Step-by-step explanation:
The sum of a number and twenty-three less than that number" as a mathematical expression is x + (x – 23)
I mean its the only answer with sum and "less than" because that usually means you need to subtract, I hope this helps
2log7 - 2r = 0
1.690196080 - 2r = 0
<u>-1.690196080 -1.690196080</u>
<u>-2r</u> = <u>-1.690196080</u>
-2 -2
r = 0.84509804

tan(65) = BC/7
BC = 7*tan(65)
