-14+71/2= -6 1/2 degrees Celsius is the original temperature.
120/4 = 30
120 x 2 = 240
240 + 30 = 270
270 grams of flour were used
Answer:
9
Step-by-step explanation:
substitute the x which is x= 2, so

Answer:
Surface area of cone is 
Step-by-step explanation:
Given:
radius of a cone (r) = 8 feet
slant height of cone (l) = 12 feet
We need to find the surface area of cone.
Total surface area of cone = Area of circle
Area of curved surface
Now we know that,
Area of circle = 
Area of curved surface = 
Hence Total surface area of cone = 
Surface area of cone is
