The correct answer is option B which is
<u>Step-by-step explanation:</u>
Given:
The dimensions of the cylinder,
Radius (r) = 12 cm
Height (h) = 9 cm
To find:
The volume of cylinder.
Formula:
Volume of the cylinder =
If r = 12 cm and h = 9 cm then the volume of the cylinder can be found by using the formula as,
Volume of the cylinder =
=
≈ 4072 cm³
So it is closest to the answer B, 4,072 cm³.
Answer:
65
Step-by-step explanation:
right angle triangle so:
a=??, b=72 and c=97
a^2+b^2=c^2
a=√c^2-b^2
a=√97^2-72^2 =65
Answer:
24x
Step-by-step explanation:
=6x×4+24x×3-72x
=24x+24×3x-72x
=24x+72x-72
=24x
The <span>time, which will show
different time from others when rounded to the nearest tenth of a second, is
4.24. The tenths place of 4.24 is below 5 which will result to 4.2. While the
tenths place of 4.28, 4,26, and 4.25 when rounded to nearest tenth of a second
will result to 4.3.</span>
Part (a)
<h3>Answer: y1 and y3 are perpendicular</h3>
This is because the two slopes 2 and -1/2 multiply to -1. Perpendicular slopes multiply to -1 assuming neither line is vertical or horizontal.
=====================================================
Part (b)
Graph each line to see where they cross. The three points of intersection are
(0,4)
(2,-2)
(4,2)
The order of the points doesn't matter.
You could also form three systems of equations pairing up the equations, and solving each system. That way you can find the points of intersection. Graphing may be a better and faster route in my opinion. See the diagram below.
