If you have tickmarks on the segment, on a blank piece of paper, then you count out the spaces to get the length of the segment. This is assuming the tickmarks are properly spaced out. If there aren't any tickmarks, then you'll have to use a ruler to find the length. Either way, a ruler is encouraged.
The coordinate plane makes things easier to find the length of any segment. Use either the pythagorean theorem or the distance formula to find the length of the segment.
Answer:
$8
Step-by-step explanation:
for a discount of 20% we require to calculate 20% of $40
20% =
= 0.2, hence
discount = 0.2 × $40 = $8
Answer:
Step-by-step explanation:
The volume of a cone is

Filling in what we have:
and simplifying a bit:

Multiply both sides by 3 to get:

Divide both sides by 12.56 to get:
and take the square root of both sides to find the radius:
r = 5
If the radius is 5 and the radius by definition is half the diameter, then the diameter is 10 inches.
I assume that you mean: the length is 7cm more than the width, and the perimeter is 74 cm.
If so, we can write down the following system, where l and w represent, respectively, the length and the width:

We can easily solve the second equation:

And finally solve for the length:
