Answer:
Diameter = 23 Radius = 11.5
Step-by-step explanation:
Divide the circumference by π, or 3.14 for an estimation. The result is the circle's diameter.
<em>72.22 ÷ 3.24 = 23</em>
diameter = 23
Divide the diameter by 2.
<em>23 ÷ 2 = 11.5</em>
There you go, you found the circle's radius
Answer:
Pi/3 radians also measures 60 degrees not 30
Step-by-step explanation:
Pi/3 x 180/pi=180pi/3pi
Since both have pi they cancel out leaving 180/3, which equals 60.
Larger Number: L
Smaller Number: L-9
Larger Number + Smaller Number = 45
L + L - 9 = 45
2L = 54
L = 54/2
L = 27
Smaller Number = L - 9
27 - 9 = 18
Check. .. 27 + 18 = 45. CORRECT!
Larger Number is 27
Smaller Number is 18
Answer:
Step-by-step explanation:
x + y = 40
x>y
(11/2)y - (13/4)*x = - 25
x = 40 - y
(11/2)y - (13/4)(40-y) = - 25 multiply by 4
22y - 13( 40 - y) = - 100
22y - 520 + 13y = -400 Add 520
35y = 120
y = 120 / 35
y = 3 3/7
x = 40 - y
x = 36 4/7
