the diagram shows 3 identical circles inside a rectangle. each circle touches the other two circles and the sides of the rectang

Sergio [31]

Answer:

2640mm

Step-by-step explanation:

I'm assuming you need the area of the rectangle which the circles don't take up.

First, to find the area of the whole rectangle:

length x width

to find length:

the length is 1 circle, therefore it is the diameter of the circle, which is 32 x 2 = 64mm

to find width:

the width is 3 circles, which is the radius 6 times, so 32 x 6 = 192mm

So, area of rectangle = 64 x 192 = 12288mm

Now to find the area the circles take up:

area of 1 circle =

$\pi \times {r}^{2}$

$\pi \times {32}^{2}$

$1024\pi$

As we have 3 circles, we multiply this by 3:

$1024\pi \times 3 = 3072\pi$

Finally we subtract the area of the three circles from the area of the rectangle:

$12288mm - 3072\pi = 2637$

As we need to round it to 3 significant figures, the answer is 2640mm
