Answer:
The expression provided by the area (square meters) is given by: 
.
Step-by-step explanation:
The area of the algae colony is a function of the radius r (meters), so 
.
The radius of the circle formed by the algae colony is a function of time t (in minutes), so 
. So,
[Substituting the expression for radius]
Then the expression provided by the area (square meters) is given by: .
8/100, 3/5, 7/10
Explanation:
8/100 = 0.08
3/5 = 0.6
7/10 = 0.7
Answer:
3053.63 un³
Step-by-step explanation:
Hello!
The diameter is 18, so the radius is half of the diameter, or 9.
Using the volume of a sphere formula: 
Solve:
- 3,053.6280592893 ≈ 3,053.63
The volume is 3053.63 un³.
Lateral Area of a Cylinder=2πrh
= 2 x π x 7 x 24
=336π
Option D
Answer:
Im not too sure given yopur formatting, but I believe you meant this: -((3/8)/(-1/4))
therfore, the answer is: 3/2
Step-by-step explanation:
You can seperate the two fractions as 3/8 divided by -1/4, which is equal to 3/8 * 4/-1, simply multiply across to get 12/-8, which simplifies to -3/2. Flip the sign to get 3/2
