Answer:
864 cubic meters
Step-by-step explanation:
Rectangular prism = 5x9x12=540
Triangular prism = 1/2(9)(6)(12)=324
540+324=864 cubic meters
If you multiply 8.5 by 50 cents your answer will be 4.25
Answer:
k = 1.2
Step-by-step explanation:
Solving for t when the account value is 30,000, we have ...
30,000 = 25,000e^(0.0198t)
30,000/25,000 = 1.2 = e^(0.0198t)
ln(1.2) = 0.0198t
t = ln(1.2)/0.0198
Matching this with the form ...
t = ln(k)/0.0198
we see that k = 1.2.
_____
k is the multiplier of account value in time period t.
Answer:
That means Circumference = PI * diameter
Therefore,
PI = Circumference / diameter
Step-by-step explanation:
Answer:
area = 81π in² (or ≈ 254.47 in²)
Step-by-step explanation:
The formula for an area of a circle is area = πr².
You are given the diameter, which is 18 in.
diameter = radius (2)
So to get radius, divide the diameter in half:
18/2 = 9.
Now that we have the radius, put that back into the formula for the area of a circle:
area= π9²
Then, solve for the 9², which will be 81 and put it back into the formula.
area = 81π in²
If you need to get rid of the π, the answer will be about 254.47 in²
