So to find a cylinder's volume, you do πr^2*h = volume
So we can fill in a few of the elements.
3.14 * 2.5 ^2 * h = 170
And then we can continue to simplify it.
3.14 * 6.25 * h = 170
19.625 * h = 170
And then to find h,
170/19.625 = about 8.66
The length is 4 and width 15. When multiplied the area equals 60 and when you add up all the sides the perimeter is also 38.
-3/5x + 1/5 > 7/20
-3/5x > 7/20 - 1/5
-3/5x > 7/20 - 4/20
-3/5x > 3/20
x < 3/20 * - 5/3
x < -15/60 reduces to -1/4
Step-by-step explanation:
1.Make a line l .
2.Make a perpendicular to this line .
3.Extend the line.
4.Extend compass for 5 cm arc .
5.Place the compass on the line l at the point of perpendicular and make arc on the extended line .
6.Draw line through the point of intersection.
Here are the answers. Sorry if the writing isn’t very clear! I hope this helps!!
