Question

pls. answer the questions​

Answer 1

Answer:

4. 23 hats

5. 3025cm³

Step-by-step explanation:

4. given, r = 3cm and h = 4cm

implies that, l = 5cm (r²+h²)

implies that, CSA (1 hat) = πrl

CSA = 47.123 cm²

thus, 1000cm²/CSA hats can be manufactured

implies that, 23.739 hats can be manufactured

since hats need to have whole number value,

23 hats can be manufactured.

5. given, h = 11cm and r = 7/2cm (d = 7cm)

v(1 cylinder) = πr²h

= 60.5 cm³

therefore, v(50 cylinders) = 50xπr²h = 3025cm³
