Answer:

Step-by-step explanation:

[(2 hours)/(1 day)](14 days)=(18+x)hours

Let's note that the unit of day is in the numerator and denominator.  It cancels

[(2 hours)/(1 day)](14 days)=(18 hours)+(x hours)

(2 hours)(14)=(18+x)hours

Let's note that the unit of hours is in the numerators of both sides of the equation.  It cancels

(2 hours)(14)=(18+x)hours

(2)(14)=18+x

28=18+x

10=x

HE WILL HAVE TO STUDY 10 HOURS.

Identify the surface area of the composite figure in terms of π.
Katena32 [7]

Answer:

  78π m²

Step-by-step explanation:

The lateral area of the cylinder is ...

  LA = 2πrh

  LA = 2π(3 m)(8 m) = 48π m²

The lateral area of one cone is ...

  LA = πrh . . . . where h is the slant height

  LA = π(3 m)(5 m) = 15π m²

Then the total surface area of the figure is the area of the two cones plus that of the cylinder:

  S = 2(cone area) + cylinder area

  S = 2(15π m²) +(48π m²)

  S = 78π m²
