Answer:
Net for the prism will have 3 rectangles with dimensions 5 by 15, 12 by 15 , and 13 by 15, and 2 triangles with legs 5 inches and 12 inches.
The correct net is net a.
Surface area = sum of areas of the three rectangles and sum of the two triangles.
SA = (5 x 15) + (12 x 15) + (13 x 15) + (5 x 12) = 75 + 180 + 195 + 60 = 510 square inches.
Step-by-step explanation:

First you would take both radius' and add them. Once you add them, subtract the sum by 42. that will give you the distance between the gap of the circles. now that you have that distance, add 19 and 11 and your result is your final answer.
in order to add picture you need to take a picture for it. you can you "snipping tool" if you have it. once you snip a picture you should save it to your desktop. if you want to post a picture on prainly there is a swirly picture on the bottom that looks kinda like a paper clip. press that it should say add attachments. then add your attachment
Answer:
let Φ be the central angle of the arc
pi*2r = 20
r = 10/pi
arc length= 2pi*r*(Φ/360°)
4 = 2pi*r*(Φ/360°)
Φ=2/10 * 360° =72° degree
Well 63% is out of 100... and .00 is in the hundredth place so it would be .63%
or 0.63%
