Answer:

Step-by-step explanation:
Circumference = 
Given that d = 7 m


The LCM (least common factor) of 12 and 27 is the number: 3
C and D are correct because 25 > 35 so that's C.
Its also D because they are not equal.
Hope this helps :)
Answer:
dV/dt = 3×10^2 × 0.5 = 150 in^3/sec
the volume of the cube is increasing at 150in^3/sec
Step-by-step explanation:
Volume V = length l^3
V = x^3
Differentiating both sides;
dV/dt = 3x^2 dv/dt
Given;
x = 10 in
dx/dt = 0.5 in/sec
dV/dt = 3×10^2 × 0.5 = 150 in^3/sec
the volume of the cube is increasing at 150in^3/sec
X=25/11 and y=17/11 if that’s what your asking for
