The area of a circle is pi(9x2 + 6x + 1) square cm. Find an expression for the length of the circles radius

r = 3x + 1

Step-by-step explanation:

The area (A) of a circle is calculated as

A = πr² ( r is the radius )

Here

πr² = π(9x² + 6x + 1) ← divide both sides by π

r² = 9x² + 6x + 1 ← perfect square

r² = (3x + 1)² , thus

r = 3x + 1

idk im srry

step-by-step explanation:

part a

in a city ice cream is mostly only bought when the temperature is very high as ice cream cools down our

so we can derive the conclusion that as the temperature increases the number of ice creams sold also increases

part b

y intercept is 5

slope is 2
