A whole circle is 360 degrees. So add up the known degrees (115+105+60)=280degrees
Then 360-280=80 degrees
Hello there! :-)
The formula for finding the area of a circle is
Notice that only the radius is squared.
We are given the radius of the circle: 21 cm.
We plug the value of r into the formula:
- A=π(21)²
- A=π(441)
- A=1,385 cm
Hope this helps. Use the comment section to clarify your doubts.

Good luck.
From the given function, to explain the correct answer I will plot the graph for :
y(t)=-t^2+14t-40
thus the graph will be as shown in the figure:
From the graph we deduce that the correct statement is:
y'(t)=-2t+14=0
thus
t=7
thus
y(7)=0
thus the correct statement is:
<span>c. The average rate of change over the interval 6≤t≤8 is 0</span>
Answer:
KL = 15
Step-by-step explanation:
Given that,
Point L is on the line segment KM.
We have, KM=5x+10, LM=4x, and KL=3x
ATQ,
KM = KL + LM
Putting all the values, we get :
5x+10=3x+4x
5x+10 = 7x
Taking like terms together
5x-7x=-10
-2x=-10
x=5
Put x = 5 in KL = 3x
KL = 3(5) = 15
So, the value of length KL is 15.
