Problems are very often written in a confusing way. This one couldn't possibly have been
written any more clearly. Sooner or later, you have to stop telling yourself that you have
no clue, settle down, and carefully read the words that are right there on the page.
I'll tell you one more detail that's not in the problem: "breadth" means "width".
Now. The problem clearly tells you all of these things, in this exact order:
=> Area of the walls = (2 x height) x (length + width)
=> length = 8m
=> width = 6m
=> height = 2.5m
Is there a reason you can't take the numbers for length, width, and height,
and write them in the formula for the area ? Do I have to do all the work ?
Area = (2 x height) x (length + width)
Area = (2 x 2.5m ) x ( 8m + 6m )
Do the arithmetic inside the parentheses:
Area = ( 5m ) x ( 14m )
Do the multiplication:
Area = <u>70 m² .</u>
You will never see a problem that comes any closer to answering itself <em>for </em>you.
Answer:Q(5,-2), S(-3,4)
Step-by-step explanation:
(-3,-4) is in the third quadrant so reflected over the x-axis results in it being in the second quadrant so only the y changing to positive giving you (-3,4)
(5,2) is in the first quadrant so when reflected over the x-axis it ends up in the fourth quadrant making y turn to negative giving you (5,-2)
Answer:
28π
Step-by-step explanation:
The formula for calculating surface area of cylinder is 2πrh+2πr^2 (r: radius, h : height)
Since the base for the given cylinder is 2 and height is 5 the surface area would be
2π×2×5 + 2π×2^2 = 28π
Answer:
it would be 4
