Find the circumference of a circle with an area of 1809.56 square centimeters

150.8cm

Step-by-step explanation:

Area= π r²

make r subject of the formula

A = π r²

A/π= πr² (dividing both sides by π)

r²= A/ π

r =

r=√(1809.56)/(π)

r=√576.0008

r≈24cm

:. circumference= 2π r

= 2× π × 24

=150.7964

≈150.8cm

Y= 4/5 x + 24
To find the rate of change you find the difference in each of the numbers on the graph. For example, 36-32 is 4. So 28-4 is 24 and that would be the next number down. It would also match x to be 0 because since the rate of change for x was 5, if you subtract 5 from 5 you get 0. So from this we know that the coordinates would be 0,5.
From this info, the slope would be 4/5 and the y intercept or initial value would be 24
