Answer:
b
Step-by-step explanation:
r=d/2=11.4/2=5.7
slant surface area=2πr*h=11.4×3.14×4.4=157.5024 cm^2
area of base and top=2(πr²)=2×3.14×(5.7)²=204.0372 cm²
total surface area=157.5024+204.0372=361.5396=361.5 sq. cm

Step-by-step explanation:
The monthly rent of the apartment in the 10th year is $1041.67.
<h3>What is the monthly rent during the 10th year of living in the apartment?</h3>
The first step is to determine the yearly rent in the first year of living in the apartment.
Yearly rent = $900 x 12 = $10,800
The second step is to determine the yearly rent in the 10th year
$10,800 + (170 x 10) = $12,500
The third step is to determine the monthly rent
Monthly rent = $12500 / 12 = $1041.67

After 24 hours, 35.4% of the initial dosage remains on the body.
<h3>What percentage of the last dosage remains?</h3>
The exponential decay is written as:
Where A is the initial value, in this case 2.8mg.
k is the constant of decay, given by the logarithm of 2 over the half life, in this case, is:
Replacing all that in the above formula, and evaluating in x = 24 hours we get:
The percentage of the initial dosage that remains is:
