Question

A caution sign is shown in the given figure. Find the area to be painted in red (shaded in figure), in order to warn the people about the danger ahead. (Use √3 = 1.732)

Answer 1

$\huge\blue{\mid{\fbox{\tt{GIVEN\:THAT:}}\mid}}$

DC = AB = 8

AD = CB = 6

$\huge\red{\mid{\underline{\overline{\textbf{To\:Find}}}\mid}}$

Let us first find the diagonal AC

$\huge\orange{\mid{\fbox{\tt{Using\:pythagoaras theroem}}\mid}}$

Since AC = the diameter of the the circle then,

R =

R =  

R = 5

●$\huge\pink{\mid{\underline{\overline{\textbf{The \:Area of a Circle =}}}\mid}}$

=》 3.14 × 5 × 5

=》78.5

●$\huge{\boxed{\mathfrak{Area of Rectangle = Length × Breadth}}}$

=》 8×6

=》 48

The area of Shaded region = Area of Circle - Area of Rectangle

=》 78.5 - 48

=》 30.5 Ans
