Answer:
The circumference of the circle is
.
Step-by-step explanation:
A sector is the part of a circle enclosed by two radii of a circle and their intercepted arc. A pie-shaped part of a circle.
The area of a circle is given by 
The formula used to calculate the area of a sector of a circle is:

The circumference of a circle is the distance around the outside of the circle and its given by

We know the central angle
= 110º and the area of the sector 50 units squared.
First, we use the formula to calculate the area of a sector to find the radius.

The radius can't be negative. Therefore,

Next, we apply the formula for the circumference of a circle.

Answer:
Step-by-step explanation:
m2 + 3m + 2
m2 + m + 2m + 2
m (m + 1) + 2(m + 1)
(m + 1) and (m + 2) are the factors
Pretty sure that would be 120. Since the angles of a triangle add up to 180, you just add 25 and 35 (makes 60) and subtract it by 180, leaving 120
Answer: 40 minutes
Step-by-step explanation:
2/5 = .4 so it would be 40 minutes
