tell me theanswer please guys​

Answer 1

Answer:

(a) 30.6 m^2

Step-by-step explanation:

First we need to find the diameter of circle

The diagonal of the rectangle is the diameter of the circle

$diagonal \: of \: the \: rectangle \: = \\ \sqrt{{8}^{2} + {6}^{2} } = \sqrt{64 + 36} = \sqrt{100} = 10m$

Area of the shaded portion=

area of circle - area of rectangle

=

$\pi{r}^{2} - lb \\ = > \pi {5}^{2} - 8 \times 6 \\ = > 25\pi - 48 = > 30.6 {m}^{2}$
