Answer:
Add all the numbers from 30 to 80 and that is your answer
Step-by-step explanation:
The circumference of a circle that was computed when the diameter is 3cm will be 9.426cm.
<h3>How to find the circumference?</h3>
The circumference of a circle of gotten by the formula:
C = 2πr or πd
where,
r = radius
d = diameter
Since the diameter is given as 3cm, the circumference will be:
= πd
= 3.142 × 3
= 9.426cm
In conclusion, the circumference of the circle is 9.426cm.

Answer:
idk this is actually hard
Step-by-step explanation:
The angle of X would equal 104 degrees. The reason behind that would be because it is a vertical angle, meaning it equals the same amount vertical to itself.
To get angle Y, you would need to add 104 and 56 together (160) to find the last angle. Knowing that all triangles equal 180 degrees, you subtract 160 from 180, resulting in 20 degrees. The angle of Y equals 20 degrees.
X = 104 degrees
Y = 20 degrees
Yo sup??
To find velocity just differentiate the function r once wrt to t
v=dr/dt=(9t^2-1)i+(4t+2)j)
and to find acceleration differentiate v wrt to t
a=dv/dt=18ti+4j
Hope this helps.
