Answer: when you rotate the triangle 180 degrees the new points would be (-1,-2), (-1,-4), and (-3,-3).
Step-by-step explanation:
You simply flip the graph 180 degrees. Not that hard.
To find the superficial area of a prism you have to do base perimeter * height
So find the perimeter of the right triangle: 9+8+5 = 22 yd
Then find the superficial area 22*12 = 264 yd^2
Answer: Density = 0.23 tons per cubic meter.
Step-by-step explanation:
Formula : 
1 ton = 32000 ounces
⇒ 1 ounce = 0.00003125 ton
⇒ 7 ounces = 7(0.00003125)= 0.00021875 ton
1 gallon = 0.00378541 cubic meter
2.5 gallons = 0.009475 cubic meter
Density=

Hence, Density = 0.23 tons per cubic meter.
Answer:
5:7
Step-by-step explanation:
Answer:
Surface area = 
Volume = 
Step-by-step explanation:
To find the surface area of our cone, we are using the formula for the surface area of a cone:

where
is the surface area
is the radius
is the height
Notice that the height, radius, and slant height make a right triangle, so to find the height,
, we can use the Pythagorean theorem:






cm
We have all we need now to find the surface area of our cone:


Now, to find the volume of our cone, we are using the formula for the volume of a cone:

where
is the volume
is the radius
is the height
Replacing values


We can conclude that the surface area of our cone is 261.6 square centimeters and its volume is 281.2 cubic centimeters.
