Is it exterior as in on a line?? because 150 in a 360 angle is too small because 3601 -150 = 210 and that's too big for a triangle as it exceeds the rule of all angles in triangles add up to 180
= -35 + 7 - 15
= -43
hope it helps
Is this algebra or geometry??
Answer:
Step-by-step explanation:
Always use your imaginary scissor:
Cut the above and below circle and the cylinder role it down-ways like a carpet and you will end up with two circles and a big rectangular.
Surface circle: 7 * 7 * 3,14 = 153.86
Surface carpet: 20 * circle exterior (or the length of the circle)= 20 * 2* 3.14 * 7
Results:
153, 86 * 2 (because we cut 2 circles from the cylinder) + 132,6 = 439.6
