Answer:
a. (x + 4)² + (y – 7)² = 3²
Step-by-step explanation:
General equation for a circle is:
(x – h)² + (y – k)² = r²
h and k are the center (h, k), and r is the radius.
They want a center of (-4, 7) so h=-4 and k=7
They want a radius of 3 so r=3
plug it into the equation.
(x – h)² + (y – k)² = r²
(x – (-4))² + (y – (7))² = (3)²
(x + 4)² + (y – 7)² = 3²

Answer:
1. 35 2. 565.5 3. 12.28
Step-by-step explanation:
1. Triangle 1 & 2: 7x3=21
You do not have to divide by 2 is since there are two triangles.
Semi-circle: 14.13
2. Trinagle: 29x19/2 = 275.5
Rectangle: 29x10 = 290
3. Triangle: 3x4/2 = 6
Semi-circle: 3.14x4/2 = 6.28
