Answer:
diameter(d)=8 in.
radius(r)= d/2= 4 in.
height(h)= 3r = 3(4) = 12 in.
Volume=r ² h
=(3.14)(4)²(12)
=(3.14)(16)(12)
=602.88 in.
Therefore, the volume of the cylinder is 602.88 in.
Step-by-step explanation:
Step-by-step explanation:
1/2 is equal to R6.
So 2 halves mean R6+R6=R12
Or
R6×2= R12
Answer:R12

Answer:
The point lies outside the circle.
Step-by-step explanation:
<u>To find where the point lies find the distance between the centre of the circle and the point :</u>
<u />
<u />

Since distance between Centre, Q and the point, Y is greater than the radius of the circle , the point lies outside the circle.
Answer:
CD = 5.9 mi
Step-by-step explanation:
Given:
∠DAC = 55°
∠DBC = 72°
AB = 2.2 mi
∠ABD = 180 - ∠DBC = 180 - 72 = 108°
∠ADB = 180 - ∠BAD - ∠ABD = 180 -55 - 108 = 17°
Using Sine Rule:


Solving for BD:
BD = 6.2 mi
From ΔBDC
Sin(72) = CD / BD
Sin(72) = CD / 6.2
Solving for CD:
CD = 6.2*sin(72) = 5.9 mi
