Answer:
c
Step-by-step explanation:
The answer is: it will decrease 4 times.
Let d be diameter and h height of a cylinder
The volume of a cylinder is:
V1 = π * (d/2)² * h = π * d²/4 * h = π * d² * h / 4
If diameter is halved, the volume is:
V2 = π * ((d/2)/2)² * h = π * (d/4)² * h = π * d²/16 * h = π * d² * h / 16
Now, let's compare them:
V1 / V2 = (π * d² * h / 4) / (π * d² * h / 16)
π * d² * h can be cancelled out:
V1 / V2 = (1/4) / (1/16) = (1/4) * 16 = 16/4 = 4
Therefore, the volume of the smaller cylinder will decrease 4 times.
3t - 15 = 2t + 10
t = 25
<Y = 2(25) + 10 = 60
<X = 4r
so
4r + 60 = 180
4r = 120 (<X = 4r)
answer
<X = 120
Answer:what you need help with
Step-by-step explanation:
m < AOB = 90 degrees. Reason:- Triangle ABC is isosceles and AO = AC.
m < BOC = 90 degrres Reason:- Its adjacent to < AOB
m < BOK = 1/2 * m < BOC = 45 degrees Reason: OK bisects <BOC
Therefore m < AOK = m AOB + m < BOK = 90 + 45
= 135 degrees (answer)
