Answer:
The correct answer is 8cm.
Step-by-step explanation:
Vol. Of cone= 1/3pi r²h
= 1/3×3.14× 8²×15
= 8×8×5×3.14
64× 5×3.14
= 320×314/100
=16×314=5024 cm³
Hope this helps:) Goodluck!
70 liters ÷ 100 samples= 0.7 or 7/10 liter per sample
Hope this helps! :)
I hope that helps, coz l've done what i know
Ok, I shall help.
Please give me brainliest answer.
So first step
25x+8+9x+2=180
We can do this because they are interior angles which add to 180 degrees.
So now we simplify.
25x+9x+2+8=180
34x+10=180
Minus 10 from both sides to get x.
34x = 170
Divide by 34 to only find x.
This leaves x=5 now we find y.
9x+2=7y+5
We can make these two equal because they are alternate angles which are always equal.
Now as we established earlier x is 5 so we substitute.
9(5)+2=7y+5
45+2=7y+5
47=7y+5
Now we minus 5 from both sides to leave 7y
47-5=7y
42=7y
Now we divide by 7 to only get y.
Y=6
X=5
Hope it helps!
