Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

(x - 6)² + (y + 1)² = 40 ← is the equation of a circle in standard form

centre = (6, - 1) and r = $\sqrt{40}$ = 2 $\sqrt{10}$

Area of semicircle = (πr²) ÷ 2

Area of semicircle:
= (3.14)(2)² ÷ 2

= (3.14)(4) ÷ 2

= 12.56/2

= 6.28
