Answer:
Area of the semi circle is given by
Area of the triangle is given by,
Area of the given figure,
In this situation, choose length and width such that 12.75=l*w. writing it as a mixed number you have 51/4=sqrt51/2*sqrt51/2 or any other combination you can use.
Answer:
Step-by-step explanation:
Diameter:
A line passing through the center of the circle touching the circle at two points, is called diameter.
OR
The chord passing through the center is diameter.
It is double of the radius.
so,
Diameter = (2) (Radius of the circle)
Radius:
Diameter divided by 2.
OR half of the diameter is called radius.
So,
Radius = (1/2) (diameter of the circle)
Area of a circle:
Area of a circle =πr^2
Using π=3.14
Area ≈ (3.14) (radius squared)
Circumference of a cricle:
It is equal to 2πr
If π=3.14, then 2π=6.28
Circumference ≈ (6.28) (radius of the circle)
Answer:
x = 3
Step-by-step explanation:
x^2 - 9 = (x+3)(x-3)
[(x + 3)*(x -3] /x+3) = x-3
x - 3 = 0
x = 3
To solve this problem, all we have to do is to closely
analyze the situation. Now we are given that the amount of saving per week is
equivalent to one fifth (1 / 5) of Ben’s weekly pay (or weekly salary).
Now we are to find the weekly pay or weekly salary that
result in weekly savings of $61.50. So we can see that actually the value of
61.50 is one fifth (1 / 5) of W, therefore:
(1/ 5) W = 61.50
W = 5 * 61.50
W = $307.5
<span>Therefore a weekly pay of $307.5 will result in a weekly
savings of $61.50</span>
