Answer:

By definition, considering a unit circle (circle centered at origin and of radius 1) the length of an arc is equal to the measurement in radians (the SI unit for measuring angles) of the angle that it subtends (to be opposite to). The length of the arc is equal to the radius of the circle.

surface area of prisms. please help with the work shown because i can't figure out how to solve these :(

8090 [49]

here: :)

I did the work, and basically i solved for the area of the faces and then multiplied that by two to get the total surface area of the faces. Then I added in the areas of the sides connecting the two faces:

just as a referral: the formulas to find the faces are as follows:

rectangle: length times width

circle: pi x r^2

trapezoid: h(base1 + base2)

and triangle: (b x h)/2
