Answer:
3
Step-by-step explanation:
first work out wax used for cone using formula 
1/3 x 3.14 x r squared x height
using this the total for the candle must be 113
formula for a sphere is 4/3 x 3.14 x r cubed
so we know 113 /3.14 / 4/3 = r cubed 
cube root 27 = 3

Answer:
Step-by-step explanation:
∠1 = 180° - 88° = 92° 
∠5 = 81° (alternate interior angles) 
∠4 = 180° - ( 81° + 64° ) = 35° 
∠3 = 180° - ( 81° + 35° ) = 64° 
∠2 = 88° - 64° = 24°

Answer: The second option and the third option are true.
Step-by-step explanation:
 The formula of the line in slope-intercept form is:
 
 Where <em>m </em>is the slope and <em>b </em>is the y-intercept.
 By definition, the y-intercept in a direct variation is 0.
 Therefore, substituting  and
 and  into the equation, you obtain:
 into the equation, you obtain:
 
 Then, the equation is:
 
 As this is a line, it is a linear function.
 Therefore, the second option and the third option are true.
