Answer:
Take out the area of the full circle first:
A= pi r^2
A= 3^2 x pi
A= 28.274 cm3
Area of smaller cirlces:
A= pi r^2
A= 1^2 x pi
A= 3.14159
Multiply by 2 as 2 circles: 6.28318
Substract unshaded from shaded: 28.274-6.28318
Area of shaded is 21.99082 cm3
Step-by-step explanation:

Area as sum: 
Area as Product: 7(d+4)
12. Area as sum: y*y+y*3
Area as Product: y(y+3)
Answer:
y = mx+b
Step-by-step explanation:
This is the equation for finding the slope-intercept form. Just plug in the numbers and you'll get your answer.
I know this doesn't give you the exact answer, but you have to figure things out on your own. It's good to get a little help, but not the direct answer.
