How can you decompose the composite figure to determine its area?

Gnom [1K]

Answer:

as two semicircles and a rectangle

Step-by-step explanation:

If you extend the radii shown, each becomes an end of the rectangle, and also a boundary for a semicircle. The result is two semicircles and a rectangle.

_____

Of course, two semicircles make a circle, so you could also decompose this to a circle and a rectangle.

A spherical balloon is inflated with gas at the rate of 500 cubic centimeters per minute. How fast is the radius of the balloon

zmey [24]

Using implicit differentiation, it is found that the radius is increasing at a rate of 0.0081 cm per minute.

<h3>What is the volume of a sphere?</h3>

The volume of a sphere of radius r is given by:

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

Applying implicit differentiation, the rate of change is given by:

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

In this problem, we have that:

$\frac{dV}{dt} = 500, r = 70$

Hence the rate of change of the radius is given as follows:

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

$19600\pi\frac{dr}{dt} = 500$

$\frac{dr}{dt} = \frac{500}{19600\pi}$

$\frac{dr}{dt} = 0.0081$

The radius is increasing at a rate of 0.0081 cm per minute.

wren and jenni are reading the same book. wren is on page 14 and reads 2 pages every night. jenni is on page 6 and reads 3 pages

Ratling [72]

If Jenni get one page closer to Wren every night and Wren has read 8 more pages then is will take Jenni 8 more nights to catch up to Wren. They will be on page 30 in their book.
