Answer:
i can't figure out out srry
Step-by-step explanation:
it's really hard
Hey there!
Since you probably have better things to do, your answer would be A: π(3)²
To back up my answer, the formula to find the area of a circle is π · R² where R = Radius. In that formula then, you just plug everything in. Since the radius is 3, you would put 3 into the "( )". Finally, just plug the rest of the equation in!

its 2 and 4
Step-by-step explanation:
Answer:
~8.7
Step-by-step explanation:
So we know that the formula for volume is 3.14 * r^2 * h.
So first we do 1738/23 to get an ugly ~ 75.6 Now he have to square root that to get r.
The square root of 75.6 is ~ 8.7
Answer:
The first term of the sequence is -120.
Step-by-step explanation:
The formula for the "nth" term of a geometric sequence is shown below:
an = a0*r^(n-1)
Where an is the nth term, r is the ratio and n is the position of the term on the sequence. For this problem we want to find what is the initial term, a0, so we will isolate it in the formula as shown below:
a0*r^(n-1) = an
a0 = an/[r^(n-1)]
We then apply the data given to us
a0 = 31.45728/[-0.8^(7-1)]
a0 = 31.45728/[-0.8^6] =31.45728 /-0.262144= -120
The first term of the sequence is -120.
