For a right circular cylinder, if the radius is tripled and the hight is shrunk down to half its size then what is the surface a
1 answer:
Answer:
Surface area of right circular cylinder = 1,122 inches²
Step-by-step explanation:
Given:
Origin radius = 7 inches
Original height = 17 inches
New radius = 7 × 3 inches = 21 inches
New height = 1/2(17) = 8.5 inches
Find:
Surface area of right circular cylinder = ?
Computation:
⇒ Surface area of right circular cylinder = 2rh
⇒ Surface area of right circular cylinder = 2 × (22/7) × (21) × (8.5)
⇒ Surface area of right circular cylinder = 1,122 inches²

Answer:
Step-by-step explanation:
(x – 5)^2 + 3(x – 5) + 9 = 0
This is a quadratic equation in x - 5.
Let u = x - 5, then the quadratic equation becomes:
u^2 + 3u + 9 = 0
We can use the quadratic formula to solve for u.
Since u = x - 5, now we substitute x - 5 for u and solve for x.
