Step-by-step explanation:
the length <em>s</em><em> </em>of the arc AC is given as :
s = r. 0
where
r = 10 is radius
0 = 90°
= π/2 rad is angle
s = 10. π/2
= 5π
= 5.3.14
= 15.7 ~ 16
Given:
The width of a kitchen is 4.2 metres.
Kitchen cupboard widths are 60 cm.
To find:
The number of kitchen cupboard that will fit in 4.2 metres.
Solution:
Let x be the number of kitchen cupboard that will fit in 4.2 metres.
Width of 1 cupboard = 60 cm
Width of x cupboards = 60x cm
We know that, 1 m = 100 cm.
Width of a kitchen = 4.2 metres
= 4.2×100 cm
= 420 cm
Now, the width of the x cupboards is equal to width of the kitchen.
Therefore, the number of kitchen cupboard that will fit in 4.2 metres is 7.
