"As shown" ? You have a picture to work with but you're not sharing it ?
Fortunately, the question includes all the information that's needed to answer it,
so I don't need to see the picture.
The volume of a cylinder is (pi) x (radius)² x (height) .
Radius = 1/2 of the diameter = 15 mm
Volume = (pi) x (15 mm)² x (30 mm) = 6,750 pi mm³ = 21,205.75 mm³ .
That's a correct answer, but the number is slightly awkward and inconvenient. Let's
change it to a bigger unit, so the number will be smaller and easier to carry around.
Remember that 10 mm = 1 cm
So (10 mm)³ = 1,000 mm³ = 1 cm³
and 21,205.75 mm³ = 21.20575 cm³
100% = 4.00
87% = 3.48
187 = 7.48
answer = $7.48
65 is the product of this
Speed (S) = Distance (D) / time (t)
First stretch
45 = D / 2
D = 45*2
D = 90 mp
How is the same distance:
Second stretch
S = 90 / t
Average speed (AS):
AS = (S1+S2) / 2
60 = [45+(90/t)] / 2
120 = 45+90/t
120-45 = 90/t
75 = 90/t
t = 90/75
t = 1,2 h

And now:
S = 90 / t
S = 90 / 1,2
S = 75 mph
Answer:
Step-by-step explanation:
<u>Use both points and find the slope:</u>
- m = (1 - 4) / (8 - 4) = - 3/4
<u>Find the line, using point-slope form and point (4, 4):</u>
- y - 4 = - 3/4(x - 4)
- y - 4 = - 3/4x + 3
- y = - 3/4x + 7
