Contact your teacher immediately if you cannot see the diagram! question 2 options: 278.7 square meters 52.5 square meters 25.9 square meters 75.4 square meters

I would go with 75.4 square meters. Since the circle in the middle has a diameter of 5.4m and on either side of the middle circle, it’s 2.2m to the edge of the deck. 5.4 + 2.2 + 2.2 = 9.8. The diameter if the deck (one large circle) is 9.8m. To find area, we use pi*radius squared. The radius of the deck is 4.9 m. 4.9 x 4.9 is 24.01. 24.01 x Pi is approximately 75.39m squared, so rounded to 75.4m squared.

First subtract 10 from both side
y^2+6y-16=0
(y+8)(y-2)=0
-8 and 2
