Answer:

Area of Poster = 23 sq inches

Step-by-step explanation:

Let say Width of Rectangular Poster = W  inches

then Length of Rectangular Post = 2W  inches

Perimeter = 2 ( W + 2W)  = 6W  inches

Perimeter given = 12 inches

Equating both

6W = 24

=> W = 4  

Width of Poster = W = 4 Inches

Length of Poster = 2W = 2 * 4  = 8 inches

Area of Poster = 4 * 8  = 32 sq inches

The radius of a sphere is increasing at a rate of 0.5 centimeters per minute. At a certain instant, the radius is 17 centimeters
Usimov [2.4K]

Using implicit differentiation, it is found that the rate of change of the volume of the sphere at that instant is of 1815.84 cubic centimetres per minute.

The volume of a <u>sphere of radius r</u> is given by:

V = \frac{4\pi r^3}{3}

Applying <u>implicit differentiation</u>, the rate of change is of:

\frac{dV}{dt} = 4\pi r^2\frac{dr}{dt}

In this problem, we have that \frac{dr}{dt} = 0.5, r = 17, thus:

\frac{dV}{dt} = 4\pi (17)^2(0.5) = 1815.84

The rate of change of the volume of the sphere at that instant is of 1815.84 cubic centimetres per minute.
