find the area of the largest circle help me out i will have points ​

Answers

Answer: 254.34 ^ 2

Step-by-step explanation:

To find the area of the circle use its formula

A = Pi * R^2                /  Area equals pie times radius squared

The two circles diameter combined is 18 meaning the radius is 9

So we plug 9 into the formula

A = 3.14 * 9^2

A = 3.14 * 81

A = 254.34 ^ 2

Shane bought an 18 pound bag of dog food. He feeds his dog pound of dog food 5/3 for each meal. If Shane feeds his dog twice a day every day, how many days will the 18 pound bag of dog food last?

Answers

Answer:

18 pounds of dog food will last 3 days.

Step-by-step explanation:

We know that he has 18 pound of dog food and he is giving 3 pound of food twice every day, so 3 * 2 would be 6. So we need 6 pounds of dog food is being fed every day. Since we want to find out how much dog food 18 pound bag could last, you would divide 18 by 6 so 18/6 would get you 3. So we know 18 bag of dog food will last 3 days.

It will last for 3 days i believe.

Which graph shows a dilation?

Third graph:

The initial shape is a rectangle.

The dilated shape is also a rectangle but the size is not dilated in similar dimensions.

So it is not a dilation.

Thus,

The first graph shows a dilation.
