Answer:
The formula for the volume of a cone is 1/3 Bh. This means 1/3 the Area of the base times the height. You can calculate the area by multiply length and width. Area is two-dimensional. Multiplying height by it adds another dimension. When writing area, we say units squared. When writing volume, we say units cubed, because it is three dimensional.

Answer:
70
Step-by-step explanation:
the red lines mean the two sides are equal
so its an isosceles triangle meaning the two angles other than the 40° one are equal
the inner angles of a triangle must add up to 180
so 180-40 = 2x
140 = 2x
x = 140/2 = 70
