Answer:
½ r² ∅
The area of a sector of a circle is ½ r² ∅, where r is the radius and ∅ the angle in radians subtended by the arc at the centre of the circle. So in the below diagram, the shaded area is equal to ½ r² ∅ .
Step-by-step explanation:
5x4=20 or divided by themby 20divby5 = 4?
The rise in temperature by 11 degrees Fahrenheit can be represented by the temperature change, ΔT = +11 °F. The temperature change is positive because the temperature increased as stated in the question. Moreover, the formula for temperature change is: ΔT = T_final - T_initial. This means that for this case, the final temperature is higher than the initial temperature.
Answer:
87
Step-by-step explanation:
all the angles of a triangle out of 180 so subtract the two numbers you have from 180
