Volume of a cone: 1/3
r²h
r is the radius (diameter ÷ 2) and h is the height.
Find the radius first using the diameter: 2
÷ 2 = 1.25
Now plug in the numbers into the formula.
1/3
1.25²10 = <span>16.4

The volume of the cone is 16.4 cubic feet.
Answer:
19
Step-by-step explanation:
fx=16+4
fx=20
gx= 20-1
gx=19
19
The answer is 80, 2x+3x+4x=180, so x=20. 20*4=80.
Answer:
4
Step-by-step explanation:
Given that three pairs of gloves- a red pair, a blue pair, and a green pair-are in a drawer. The gloves are removed at random without returning any to the drawer.
We have to find the minimum number that must be removed in order to guarantee having a matched pair of gloves
No of different colours = 3 (red, blue, green)
Hence no of gloves that must be removed = 3+1
If 4 gloves are removed, only 3 can be of different colours 1 will have same colour as any one of the three.
So a pair of same colour would be obtained
Answer is 4
2x+y-3=0,x-2y=1 okay that's the answer good luck
