The radius is given as 21 cm and pi = 3.142
Circumference = 2 x 21 x 3.142 = 131.964 cm
The coefficient of these two number are -24 and 7. :)
Answer:
21
Step-by-step explanation:
because
Given, the rate of growth of St. Augustine grass is cm per week.
We have to find the number of weeks that the grass grow to cm.
Let's take the number of weeks be x.
In 1 week the grass grow = cm
So in x weeks the grass grow = cm
So we can write,
To solve it for x, first we will move 7 to the right side by multiplying it to both sides. We will get,
Now to get we will move 4 to the right side by dividing it to both sides. We will get,
So we have got the required answer.
After 3 weeks the grass grow .
