Answer:
-1/3 is closer to 0
Step-by-step explanation:
3/8 is between 0 and -1/3. We need to determine if 3/8 is closer to -1/3 or closer to zero. Since -1/3 is smaller than 3/8, 3/8 is closer to -1/3. Since 3/8 is closer to -1/3, 3/8 rounded to the nearest -1/3 is -1/3.
So you know that the formula to find the volume of a cone is V=pi x r^2 x h/3
We know that pi is 3.14 so you plug that number in for the pi symbol. Then we know that r is the radius. Since the diameter is shown in the word problem divide 14.8/2 because the radius is half of the diameter. You should get 7.4 as your radius. Then we already know the height for h/3 which is 8.1. Now that you have all of the information given substitute the formula and you should get:
V=3.14(7.4)^2(8.1/3)
Multiply 3.14 times 7.4 to the second power in which you will get 171.3498
Then, divide 8.1 by 3 and then you should get 2.7.
Multiply 171 by 2.7 (btw I rounded 171.3498 to the nearest tenth) and your final answer should be about 464.
Hope this helps
And if I’m wrong please correct me.
Answer:
1-1) A=6×5=30m² | P=6×2+5×2=12+10=22m
1-2) A=5×20=100mi² | P=5×2+20×2=10+40=50mi
2-1) A=16×6=96m² | P=16×2+6×2=32+12=44m
2-2) A=20×9=180km² | P=20×2+9×2=40+18=58km
3-1) A=14×17=238yd² | P=14×2+17×2=28+34=62yd
3-2) A=20×18=360mi² | 20×2+18×2=40+36=76mi
Answer:
-2/3
Step-by-step explanation:
the triangle on the line is 2 by 3 and the slope formula is:
rise over run aka length over height!
Since the line is going downhill it would be negative!
