Answer:
Volume = Length × Width × Height
Volume = 10 × 3 × 2
Volume = 60 cm
in 15 hours Alexandra makes 7.5 boxes. how many boxes can she make in one hour?
so 15 hours=7.5 boxes
divide both sides by 15 to get hours
1 hour=7.5/15
answer is 1 hour=0.5 boxes
hope this helped you :)
75-25 = 50 It looks like the sides are 25, 25, 25 so it is really equilateral.
If I thought that the side given 25 had the equal side then it would be 25 with 25 left over for the other side.
If I thought the given side, didn't have an equal side, I would have subtracted 25 and divided by 2 like I did originally.
Equilateral triangles have equal sides and equal angles. So.. each angle must be 60 degrees.
To find the total surface area of this cone, we have that the total lateral area is given by the formula:
Where
s is the slant height of the cone, s = 12 inches.
r is the radius of the base of the cone, r = 7 inches.
To that area, we need to add the area of the base of the cone:
That is, this is the area of a circle with this radius. Then, the total surface area is:
Substituting the values in this formula, we have:
Then
Hence, the total area is equal to 417.62 square inches.
