Answer:
5
Step-by-step explanation:
Im asuming you meant " x = 2 ".
According to PEMDAS, parenthese come first so...
10 - ( 2 + 3 )
= 10 - 5
= 5
Given dV/dt , find dh/dt.
Use volume formula for cone.
Define radius in terms of height.
Differentiate with respect to 't'.
Sub in given values, dV/dt = 12, h=2.
Solve for dh/dt.
Answer:I think 4th option
Ok find circumference sinc that is what touches the grownd
C=pid
d=2.5
c=2.5pift
aprox pi=3.14 for problem
c=2.5(3.14)
c=7.85ft
how many 7.85ft does it take to get 5280 ft
7.85 times how many=5280
divide both sides by 7.85
how many=672.611
tenth
672.6
answer is 672.6revolutions
