Answer:
Step-by-step explanation:
SA= 2*r*r*pi + 2*pi*r*h
= 2*6*6*3.14 + 2*3.14*6*8
Answer:
D
Step-by-step explanation:
A is (-8,8) so you would divide each 8 by 4 because 8 divided by 1/4 so you will have (-2,2)
B is (-8,4) so divide the by 1/4 which would be (-2,1)
C is (4,-4) so divide that and and you get (1,-1)
Answer:

Step-by-step explanation:
You can use the work they gave you and continue from there:

First, simplify the numerator:

Finally, simplify the denominator:

Answer:
90 degrees
Step-by-step explanation:
A triangle equals 180
180 - 60
= 120
120 - 30
= 90
Also you can easily get the answer without doing any math because you can see the angle is a right angle
Right angles equal 90
Hope this helps dude
