6/10÷3=0.2 i don't know if you want an explanation
It's 34.
You can either intuitively know 25% means one-fourth and divide 136 by 4
Or
Convert the percentage to a decimal and multiply. 136 * 0.25 = 34
So each 1 revolution it travels the distance around the rim of the wheele aka circumference
circumference=pi times diameter
diameter=21
circunference=pi times 21 or 21pi
so distance=number of revolutions times circunference
number of revolutions=3
subsitute
distance=3 times 21pi
distance=63pi
answer is 63pi
or aprox pi to 3.14 and do 63 times 3.14=197.82
aprox 197.82 inches
First,

The volume is given by the integral (one of 6 possible combinations),

Recall that the interior angles of a quadrilateral add up to 360 degrees.
1) Let x be the measure of the missing angle, then we can set the following equation:

Solving for x we get:

2) Let y be the measure of the missing angle, then we can set the following equation:

Solving for y we get:

Answer:
1) 100 degrees.
2) 58 degrees.
