The volume of a pyramid is one-third the volume of a prism.
The formula for the volume of a pyramid is V = 1/3Bh
1)y=3x
2)y=x
3)y=7x
4)y=x+7
4)y=2x+1
6)y=12x+2
Answer:
k=9
Step-by-step explanation:
First find r=22/20=1.1
The sum of the first k terms formula is a1•(1-r^k)/(1-r)
a1=20 and the sum is 271.59
Now plug in these values in the formula and find k.
271.59=20(1-1.1^k)/(1-1.1)
When you simplify this equation, you will get k=ln(2.358)/ln(1.1)
k=9
