Area of a triangle = 1/2 x base x height
using the given information: area = 40 and base = 20
you now have 40 = 1/2 x 20 x height
divide both sides by 1/2
80 = 20 x height
divide both sides by 20
height = 80 / 20
height = 4 in.
If it’s a triangle I’m going to assume it’s 70 degrees

Answer: 105.84 cm^2
To find the answer, first you have to start by finding the percent of the circle in the sector. Convert the radians given to 108 degrees. 108 out of 360 is 30%.
Now, find the area of the circle. It's pi x r^2, so the area is 352.810.
Multiply this by 30% to find our area of 105.84 cm^2
