(a) 4280 = 2300 + 60c, so 60c = 1980, and thus c = 33 copies
(b) 60(21) + 2300 = $3560
The top surface area of the wedge with central angle of π / 2 radian is 9π / 4 inches square
<h3>How to find area of a sector?</h3>
The area of the top surface of the the wedge is the area of a sector.
Therefore,
area of the top surface = ∅r² / 2
area of the top surface = π / 2 × 3² × 1 / 2
area of the top surface = π / 2 × 9 × 1 / 2
area of the top surface = 9π / 4
area of the top surface = 9π / 4
area of the top surface = 9π / 4 inches squared

John should receive about 7200 milligrams of the drug.The unit conversion given is,1 lb =0.45 kg.
<h3>What is weight?</h3>
The weight of matter is found as the product of the mass and the gravitational acceleration.
Unit conversion;
1 lb =0.45 kg.
Dosage of a drug = 200 mg / kilogram
John weighs = 80 lb
1 lb =0.45 kg.
80 lb = 36 kg
According to the weight the drug should he receive is;
Dosage of a drug = 200 mg / kilogram × 36
Dosage of a drug = 7200 milli gram
Hence, John should receive about 7200 milligrams of the drug.
