Excel has a pie chart option, which you can use to draw the chart, the result

Hey...i'm just doing some revision 4 some maths, and i need help with some stuff...
Some sun bathers were surveyed when asked "Can you swim 200m non stop? 40% said yes, 30% said no, 20% said they were not sure and the rest said that they could not swim at all...
Represent this information on a Pie Graph below. Show workin' etc...
also there's one other thing...i have a ladder that's 5 m high and it's leanig against a wall, where the top of the ladder reaches just to the top, and the base of the ladder is 3 m away from the wall.
I'm trying to find out how high the wall would be...would the 3 m at the base, take off the height of the ladder, so in actual the ladder is higher than the wall or...
Would the Formula be: A= Base x Height divided by 2 of what?
first you should know that "percent" means out of 100, so 40 percent is 40/100 = 0.4
also, "of" means multiply, so to find 40 percent of 360 degrees, we find
40/100 x 360 = 144
so the 40% who said yes, will take up 144 degrees of the pie
the rest are calculated similarly
Let the two sides of the right triangle be a and b, and let the hypotenuse be c. By Pythagoras' theorem, we have:
a^2 + b^2 = c^2
here you have a and c, so plug them in and solve for b
for the second question, use your table to plot the points you got and draw the line. then look for 11 on the y-axis. draw a horizontal broken line from the 11 to the line you graphed, and then a vertical broken line down to the x-axis. the line will cut the x-axis at the required x-value
