What is the areaof a circle having a given diameter. d=16 cm

Answers

Answer 1

Answer: Area = $\pi r^2$ so if the diameter is 16, radius (r) = 8

3.14 * 8^2 = 3.14*64 = 200.96 is the approximate area

If you're looking for the answer in terms of pi, 64pi is the answer.

The sum of two numbers is 37. the greater number is 5 more than three times the lesser number. what is the lesser of the two numbers?

Answers

Hi there!

In order to solve this problem, we should first write this into expressions.

Let x = the bigger number
Let y = the smaller number

x + y = 37
x = 3y + 5

Now, we can use substitution of the system ofinequalities to solve.

We substitute the value of x into the equation.

3y + 5 + y = 37

Now, we simplify.

4y + 5 = 37
4y = 32
y = 8

So, 8 is the answer.

Hope this helps!

3y+y+=37 that’s the answer to that
