Formula= angle/360° x pi r^2
100/360 = 0.27777778
Radius = diameter/2
9.3/2 = 4.65
Pi x 4.65^2 = 67.9290872 (do not round until the end)
0.27777778 x 67.9290872 = 18.869191
This number rounds to 18.9
Hope this helps

To get the answer we can subsittute first equation into second.
x+6y=20
y+6+6y=20
6+7y=20 /-6
7y=14 /:2
y=2
Now we can back substitute
x=y+6
x=2+6
x=8
Finally we get
x=8
y=2

1650(1+i)^3 = 2262.7
<span>divide both sides by 1650, take the cube root, then subtract 1 to get i, the annual rate expressed as a decimal. </span>
Answer:
They have to go 30 m below sea level to reach wreckage.
Step-by-step explanation:
jane and her friends are diving to explore a wreckage from a ship that is 40 meters below sea level the platform they dive from is 10 meters above sea level.
Below sea level means = -40 m
Above sea level means = +10 m
It means,
-40 m + 10 m
= -30 m
Hence, they have to go 30 m below sea level to reach wreckage.
