Answer:
3/4 is 75/100 or 0.75
Step-by-step explanation:
Answer:
V = (1/3)pi(r^2)h (the first one)
Answer:
Option A. 
Step-by-step explanation:
we know that
The measure of the inner angle is the semi-sum of the arcs comprising it and its opposite.
substitute the values
Angle D is equal to Angle B because AB and DE are parallel to each other.
AD is a straight line so the (2) 2x angles and 72 degrees need to equal 180.
Setting up the equation you have:
2x + 2x + 72 = 180
Simplify:
4x + 72 = 180
Subtract 72 from each side:
4x = 108
Divide both sides by 4:
x = 108 / 4
x = 27
Answer:
87.75
Step-by-step explanation:
19.74 + 72.73= 92.47
92.47 - 4.72 = 87.75
