Answer:
2 cm
Step-by-step explanation:
h = 14 cm
Curved surface area of a right circular cylinder = 88 cm²
2πrh = 88

Diameter = 2 * r = 2 * 1 = 2 cm
The answer is 16 use pendas
(g-f)(x)=g(x)=f(x)
(g-f)(x)=6x-4+x^2
(g-f)(x)=x^2+6x-4 then:
(g-f)(3)=3^2+6*3-4
(g-f)(3)=9+18-4
(g-f)(x)=23
So the first one is -0.5 and second is -0.5 the third one is -0.5 and the fourth is -0.25 so I would say that is D
The answer is A
there is not enough hours to build everything and A has the right equation
