Answer:

x= \frac{y-4}{7}

Step-by-step explanation:

y=7x+4

Subtract 4 from both sides.

y-4=7x+4-4

y-4=7x

Divide by 7 on both sides.

\frac{y-4}{7} =7x/7

x= \frac{y-4}{7}

A kintted pot holder is shaped like a circle. It's radius is 4.5 in. What is the area?
lesya [120]

Answer:

A =63.585 in^2

Step-by-step explanation:

The area of a circle is found by

A = pi r^2

A = pi (4.5)^2

A = pi(20.25)

We can approximate pi by 3.14

A = (3.14) (20.25)

A =63.585 in^2
