The diameter of the cell model according to the taks content is; 14in.
<h3>Diameter of the cell model</h3>
Volume of paint = 615.44 square inches
π = 3.14
Volume of a sphere = 4πr²
615.44 = 4 × 3.14 × r²
615.44 = 12.56/r²
r² = 615.44 ÷ 12.56
r² = 49
r = 7
Hence, the diameter of the cell is; 2 × r = 2 × 7 = 14in.

Answer:
The Answer is C.
Step-by-step explanation:
To convert ANY percent to a decimal we need to divide the percent by 100. Lets do it:-
60%
60 ÷ 100 = 0.60
60% written as a decimal is 0.60.
CHECK OUR WORK:-
0.60 × 100 = 60
We are RIGHT!!!
So, 60% written as a decimal is 0.60 (0.6).
Hope I helped ya!! xD
Answer:
7x-5
Step-by-step explanation:
A = $ 861.69
Equation:
A = P(1 + rt)
Calculation:
First, converting R percent to r a decimal
r = R/100 = 5.5%/100 = 0.055 per year,
putting time into years for simplicity,
1 quarters ÷ 4 quarters/year = 0.25 years,
then, solving our equation
A = 850(1 + (0.055 × 0.25)) = 861.6875
A = $ 861.69
The total amount accrued, principal plus interest,
from simple interest on a principal of $ 850.00
at a rate of 5.5% per year
for 0.25 years (1 quarters) is $ 861.69.
