Answer:
x y
0 -1
-1 0
-8 7
Step-by-step explanation:
y = -x - 1
when x = 0, y = -1
when y = 0
0 = -x - 1
x = -1
when x = -8,
y = -(-8) - 1
y = 7
Answer:
157 cm^2
Step-by-step explanation:
1) find the radius
radius = side of the square /2 = 10 /2 = 5 cm
2) notice that four semicircles are equals to two circles
3) find the area of the shaded region
A = radius^2 x pi x 2 = 5^2 x pi x 2 = 157 cm^2 (round the nearest whole number)
