Answer:78.5
Step-by-step explanation:
First you find the volume of a cylinder then you plug in the answers don't forget that to find the radius you do diameter divided by 2
It is either 0.80 or 80% I believe
Answer:
18.05 g
Step-by-step explanation:
The multiplier of the initial quantity is ...
(1/2)^(t/1690)
so, for t=250, this becomes ...
(1/2)^(250/1690) ≈ 0.902545
Then the quantity remaining of the initial 20 g is ...
(20 g)(0.902545) ≈ 18.05 g
I'm assuming you mean

we can factor that sum of perfect cubes from

into

so therefor

that is simpliest form
Step-by-step explanation:
Arc length formula is

where x is radinas.
A semi circle has a radian measure of

The radius is half of the diameter, 12 so the radius is

So the arc length is

Area of semi circle is

where r is the radius.
