Answer:
6 cm
Step-by-step explanation:
The volume of a cone = (1/3) πr²h
72π = (1/3) π r² 6
72 = (1/3) r² 6
Divide both sides by 6
12 = (1/3) r²
Multiply both sides by 3
36 = r²
So r (radius) = 6 cm
All the answers except C has a Vertical Line when graphed. It must pass the Vertical line test in order to be a function.
Vertical Line Test: If you can draw a vertical line anywhere on a graph so that it hits the graph in more than one spot, then the graph is NOT a function.
C.) can pass the test since it's a horizontal line.
Hope this helps!
4 because a 45-45-90 triangle has a side ratio of 1-1-sqrt2 with sqrt2 being the hypotenuse
Answer:
5X²+16X+8=0
Step-by-step explanation:
5(X+2) (X+2)=4(X+3)
5(X²+2X+2X+4)=4(X+3)
5(X²+4X+4)=4(X+3)
5X²+20X+20=4X+12
5X²+20X-4X+20-12=0
5X²+16X+8=0
Answer:
The shorter side should be cut to 23. 3cm
Step-by-step explanation:
The area of the required paper should be equal to the area of the paper available.
35×20=30(30-x)
700= 900-30x
30x=900-700
30x= 200
30x/30= 200/30
x=6. 66
