5 n - 4n = 15 + 6
n = 21
Answer:
a) 235.62 cm³ (nearest hundredth)
b) 2. tripling the height to 9 cm, while the radius remains 5 cm, gives the most volume
Step-by-step explanation:
volume of a cylinder =
(where r is the radius and h is the height)
Given:
a) ⇒ volume =
cm³ (nearest hundredth)
b) Given:
⇒ volume =
cm³ (nearest hundredth)
Given:
⇒ volume =
cm³ (nearest hundredth)
Therefore, 2) tripling the height to 9 cm, while the radius remains 5 cm, gives the most volume
