Volume of a cone, V = πr^2h/3
r = Sqrt 3V/πh = Sqrt [(58.9*3)/(3.14*9)] = 2.5 cm, minimum
Surface area, A = πr [r+ Sqrt (h^2+r^2)] = 3.14*2.5*[2.5+ Sqrt (9^2+2.5^2)] = 92.95 cm^2
Therefore, minimum amount of paper required is 92.95 cm^2
Answer:
Step-by-step explanation:
<u>We know that:</u>
- Angles ∠A and ∠B are 28° and 37°.
<u>We don't know:</u>
<u>So, we do this:</u>
- Add the 180°
- Solve the equation 180 - 28 - 37
<u>Solve:</u>
Angle ∠C is 115°.
