Answer:

Step-by-step explanation:
In order to find the area of a square you take the base and multiply it by the height.
Base x Height = Area
In this case you have 7cm as the base and 6cm as the height.
All you have to do after that is multiply the two together.
Make sure that you remember to put the unit (cm) and make sure that it is
because some teachers are uptight about that stuff.
Hope this helped!

Step-by-step explanation:
Given
One plain pizza and two sodas cost $15.95
Similarly, 3 plain pizzas and 5 sodas cost $45.90
Suppose the cost of single pizza and soda be
and 
In linear equation format, it can be written as

Therefore, the above two equations represents the given situation.
A possible answer would be 32*0.01
Just draw a triangle(front view) and the slant/inclined sides of it are known to be 8 and you found out radius as 3.26. so mark the diameter by doubling radius.
so the material required would be a slice(like pizza slice) of a circle of radius= 8 and arc length = circumference given ,that is 20.5
now using this find the area of sector/slice. its the answer to the last bit.
now coming to next question, go to the kitchen and take any can and measure its dia and height by using a scale. and you might already know the formula to find the suface area of cylinder.
