Due to given condition we can conclude:
H = 2D
where D is diameter of base and H height of cone
Volume of cone is calculated by:
V = B*H = r^2*pi*H
Now we need to express H in terms of r. H = 2D = 2*2*r because D = 2r
V = r^2*pi*4r = 4r^3*pi
Answer:
Concept: Unit Price & Algebraic Representation
- You have 12 oz
- You have a total price of 2.10
- Hence you divide 2.10/12
- Your result to the nearest tenth is 0.2

Answer:
320cm^2
Step-by-step explanation:
Surface area is the sum of areas of each side of the shape:
Area of cross section x 2 = 1/2 x 8 x 2 x 15 = 8 x 15 = 240cm^2
Area of base = 15 x 2 = 30cm^2
Area of slope = 17 x 2 = 34cm^2
Area of back = 8 x 2 = 16cm^2.
Now, surface area of whole shape is the sum of these areas:
16+30+34+240 = 320cm^2
