Find the surface area of the composite figure

nataly862011 [7]

solution given:

For Cuboid

length[l]=11mm

breadth [b]=9mm

height[h]=6mm

For semi cylinder

height[H]=11mm

radius[r]= $\frac{9}{2}=4.5mm$

Now

Totalsurface area=2(lb+bh+lh)+½(2πr(r+H))-l*b[/tex]

:2(11*9+9*6+11*6)+22/7*4.5(4.5+11)-11*9

:438+219.2-99

:558.2mm²

Here area of base is subtracted as it is not included.

Total surface area of composite figure is :558.2mm².

32% of 35 pages please help

zepelin [54]

In order to answer this, first convert every percentage into decimal value.
The decimal value of 32% is 0.32. We just move two decimal places to the left.

Next move is to multiply the converted percent to the whole or total.
So,
= 0.32 * 35
= 11.2
Take note, there are no decimal pages. So the final answer is 11.
There are 11 pages.
