Area of a circle is given by pi*r^2
you are given the diameter which is 2r, so divide by two to find r, and get 4.85 for r
now plug in (4.85^2)*3.14
this gets you 73.9
ANSWER: 73.9
Answer:
<h2>
a(n) = -2*(3)^(n-1)</h2>
Step-by-step explanation:
The sequence -2, -6, -18, -54, ... is a geometric one, since each new term is 3 times the previous term. In other words, 3 is the common ratio.
The general formula for a geometric sequence is
a(n) = a(1)*(r)^(n - 1), where r is the common ratio and a(1) is the first term.
Here,
a(n) = -2*(3)^(n-1)
First do 294 divide by 7 that gives you 42
Next multiply 42 by 11 and u will get 462
So your answer is 462 words in 11 minutes
