Answer:
Step-by-step explanation:
In order to find the area of a circle we multiply π by the radius, and to find the radius of a circle we have to look at the line that stops directly in the middle of the circle.
Once we then have the radius, we simply multiply the radius, (with an exponent of 2) by π and then we will have our answer. Of course, round if needed.
Hope this helps.
Well, what I would do [not sure if it's the correct way], is use the white area as a sector of a circle. The top right of the box is the center of the circle, so the radius is 6.
Then, by the white portion being one quarter of the circle (90° out of 360°), I could calculate the that pink shaded region = the total square (6×6) minus the white sector.
So area (A) of white sector (s): A(s) = 1/4×pi×r^2
36 - 28.27 = 7.73
Answer:
5 x^2 - x + 6
Step-by-step explanation:
- (x^2 + 2) + 6 x^2 - x + 8
- x^2 - 2 + 6 x^2 - x + 8
(6 x^2 - x^2) - x + (8 - 2)
5 x^2 - x + (8 - 2)
= 5 x^2 - x + 6
The sum of all three angles of a triangle is always 180 degrees.
Step-by-step explanation:
4)
45 + 35.8 = a
180 - a = ?
5)
100 + 40.7 = a
180 - a = ?
6)
90 + 16.5 = a
180 - a = ?
ANSWER:
4) x = 99.2 (a is 80.8)
5) x = 39.3 (a is 140.7)
6) x = 73.5 (a is 106.5)
Answer:
$1.00
Step-by-step explanation:
Dimes = 10 / Nickels = 5 / Quarters = 25
6(10) + 3(5) + 1(25)
60 + 15 + 25 = 100 so that makes it $1.00
