Answer: 
Step-by-step explanation:
Given
Height of cylindrical cake is 
slice is removed
Volume of the slice is 
Area of slice is

Volume of slice will be multiplication of area and height

Hence, the radius of the cake is 
Answer:
J.
Step-by-step explanation:
It crosses through (0,0) and has a slope of 2.5 or rather 5/2 because when the x value is at 4 the y value is at 10 that simplifies to 5/2 or 2.5.
I would say that (d) is the correct answer because the section between x=4 and x=6 is not linear but exponential but it is still increasing. The section between x=1 and x=3 however is linear and therefore his answer is incorrect.
102 + 31 = 133
180 - 133 = 47
Your missing angle is 47.
Hope this Helps!!
Good Luck!!
Z= 90
It’s a circle theorem, drawing a triangle from a diameter of a circle creates a right angle
And then there’s always 180 degrees in a triangle, so
Y= 40
