Answer:
yes
Step-by-step explanation:
first term.
a= 80
second term. a2=10
so Common ratio r=a2/a =10/80=1/8=0.125
checking for the validity of common ratio.
a2×r=10×1/8=10×0.125=1.25 =a3= Third term.
Hence it is true.
Now 4th Term =1.25/8=0.15625
It can be observed that 4TH term Has digit that is 5 places past the decimal point.
Hence, 0.15625 is the terminating number as per the question.
So the required sum is.
S=a+a2+a3+a4
->S=80+10+1.25+0.15625
->S= 91.40625
Hope it helps...

Why?</h2>
Before solving the problem, we must remember the following:
So, for tan(45°) we have:
Also, for sin(30°), we have:
Then, substituting and dividing, we have:
So, the answer is 2.
Have a nice day!
Answer:
200.96 ft²
Step-by-step explanation:
The question is on surface area of a closed cylinder
Formulae= SA=2 ×pi× r² + 2×pi×r×h
Where pi=3.14
SA= 2×3.14×2² + 2×3.14×2×14
SA=25.12+175.84
SA=200.96 ft²
Answer:
Step-by-step explanation:
Hi! :)
You didn't provide any numbers, but the formula to find volume of a rectangular prism is:
V = L × W × H
V = volume
L = length
W = width
H = height
Hope this helps!
