Answer: 320°
Step-by-step explanation:
This is a circle geometry.
The arc length of the circle is given to be 8πcm and the radius is 4.5cm.
Now the length of an arc of a circle is
Arc length = πr0°/180° or 2πr0°/360°
To find the angle 0° subtend at the center we equate the arc length with the formula and solve for 0°.Now we go
πr0°/180 = 8π, convert to a simple linear equal and solve for the angle.
πr0° = 8π × 180
0°. = 8π × 180
-----------
π × r
= 8 × 180. 8 × 180
-------- or ---------
9/2. 4.5
= 8 × 180 × 2
------------
9
= 8 × 20 × 2
= 320°
or 8 × 180/4.5
= 1440/4.5
= 320°
To check for
equivalence, use properties of operations such as the Distributive Property.
Two expression are said to be equivalent if they resulted in the same number
after evaluation of each. You can both expand and factor expressions to
generate equivalent expressions.
24.5 x 0.25 = 6.125 acres that will be used for the new park.
24.5 x .72 = 17.65 acres in the second property
