The answer is 441 by multiplying the number of red cars with 7
Answer:
one variable data table has only one input cell and many result cells. A two-variable data table has two input cells, but only one result cell. If you look at the bar graphs, histograms, and circle graphs, they all look at one variable at a time and display the number of times or percentage of times an individual point or interval is counted. These are displays for a one variable data set. Two variable data sets give measures of two attributes for each item in a sample. Such as - eye colour & hair colour, grade & gender.

your calculations for volume (pi x r^2 × h) and surface area (2 × pi × r (h+r)) are correct. However your ratio are incorrect. From the formulas the ratio of surface area to volume would be r×h:2(h+r)
Answer:
4 lipsticks
Step-by-step explanation:
15+15=30, 30+30=60
Surface area is the total area of the 2d cutout you have shown, because if folded it would be the area of the surface. Remember that each side of a rectangle has the same value on the other side. For example, where "2ft" is placed on the far left of the diagram, the side just to the right of it would also be 2ft. Once you have these values all written down, you can evaluate the area of each individual box within the entire diagram by multiplying the width by height. Once you have the area of each individual box, add all the area values together to find the surface area.
