R1² π : r2² π = 9 : 1.44
r1 : r 2 = 3 : 1.2
r2 = 1.2 · r1 / 3
r 2 = 0.4 · r1
If the two cylinders are similar than also: h 2 = 0.4 · h 2
V 1 = r1² · π · h1
V 2 = ( 0.4 r1)² π · 0.4 · h1 = 0.064 r1² · π · h1
V 2 ( small cylinder )= 0.064 · V 1 ( large cylinder )
851.22 m³= 13.300.25 m³ · 0.064
Answer: C )
Answer:
8:30 PM
Step-by-step explanation:
Let's say that x is minutes since 6:20 PM, and y is position in miles.
Since Jonathan drives at a constant rate, the position vs time graph is linear. Two points on the line are (0, 75) and (20, 85). The slope of the line is:
m = Δy / Δx
m = (85 − 75) / (20 − 0)
m = ½
So the equation of the line is:
y = ½ x + 75
We want to find x when y is 140.
140 = ½ x + 75
65 = ½ x
x = 130
So 130 minutes after 6:20 PM is when Jonathan's position will be 140 miles. 130 minutes is 2 hours and 10 minutes. So the time will be 8:30 PM.
Answer:
The enlargement ratio is 3:4
Step-by-step explanation:
We are given
a width of 16 units and length of 12 units
so,
and
now, we can find enlargement ratio
we can use formula
enlargement ratio = (length)/(width)
now, we can plug values
now, we can simplify it
So,
The enlargement ratio is 3:4
Answer:
34.04 cm²
Step-by-step explanation:
Formula for a trapezoid:
a + b ÷ 2 × height
Substitute the values:
11.7 + 3.1 = 14.8
14.8 ÷ 2 = 7.4
7.4 × 4.6 = 34.04
The answer is 34.04 cm²

( little 10 though like the -5 is )
