Answer:
Step-by-step explanation:
Total surface area = 2πr(r+h)
If the total area of the bigger cylinder is 400cm² and radius is 4cm, then;
400=2(3.14)(r)(r+4)
400= 6.26r(r+4)
400=100.48 + 25.12h
299.52 = 25.12h
H = 299.52/25.12
H = 11.92cm
For the smaller cylinder
The height is calculated as;
H/h = R/r
11/92/
Answer:
a. Relative Growth rate = 10% (6/60 * 100)
b. Number of cells after t hours = 50 * 1.1^t
c. Rate of growth after 6 hours = 77.2% (1.1⁶ - 1)
d. The number of cells after 6 hours is
= 89 cells
Step-by-step explanation:
A cell divides into two cells every 20 minutes
In one hour, the cell will divide into 60/20 * 2 = 6 cells
Each cell growth 6 cells per hour
Initial population of a culture = 50 cells
t = time in hours
a. Relative Growth rate = 10% (6/60 * 100)
b. Number of cells after t hours = 50 * 1.1^t
c. Rate of growth after 6 hours = 77.2% (1.1⁶ - 1)
d. The number of cells after 6 hours = initial population * growth factor
= 50 * 1.772
= 88.6
= 89 cells
Answer:
Step-by-step explanation:
the formula for a circle which would be C = 2 \pi r
The 9.5*3.14 divide by two so 14.915
and this rounded would be 15.0 or 14.9 not too sure just pick whatever
Answer:
Step-by-step explanation:
0.31=0.3100
0.409=0.4090
0.414=0.4140
0.4186
arranging smallest to largest
0.3100,0.4090,0.4140,0.4186
or 0.31,0.409,0.414,0.4186
