The answer should be 3 :)
Answer:
I think it would be 3/4
Step-by-step explanation:
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
.
The surface area of the hemisphere with radius r = 19 cm. is 3400.62 square centimeters
<h3>How to determine the surface area?</h3>
The radius is given as:
r = 19
The surface area of a hemisphere is:
Area = 3πr²
So, we have:
Area = 3 * 3.14 * 19²
Evaluate
Area = 3400.62
Hence, the surface area of the hemisphere is 3400.62 square centimeters
