The formula for radius is R=\frac{C}{2\pi }.

First we need to see what 8*π is, put it in your calculator and you will get . So now we know the exact circumference, so now put that into the equation to find the radius.

R=\frac{25.1327412287}{2\pi } =4

Hope this helps, now you know the answer and how to do it. HAVE A BLESSED AND WONDERFUL DAY!

Answer:

The answer is, 4 cm

Step-by-step explanation:

The radius of a circle can be calculated using the circumference, to find it we will use the following formula:

r =   \frac{C}{2\pi }

we have to;

\pi = 3.14 (it is a cost)

C = 8\pi

C = 8 × 3.14

C = 25.12

then we replace in the formula;

r =   \frac{25.12}{2\pi }

r =  \frac{25.12}{2*3.14}

r =  \frac{25.12}{6.28}

r = 4.

Harry saved $100 each week for 8 weeks. He earned $48 on his savings of $800. What interest did Harry earn for every $100?
ch4aika [34]
<h2>Explanation:</h2><h2></h2>

In this problem, we know that Harry saved $100 each week for 8 weeks. In other words, he saved a total amount of money:

\text{Amount of money saved}=8\times 100=\$800

We know that he earned $48 on his savings of $800, so for every $100 the interest (I) he earns is:

I=\frac{48}{8}=\$6

So, in conclusion Harry did earn $6 in interest for every $100

A scientist needs to make 2 liters of saline solution (salt water), in which the salt
gulaghasi [49]

Answer:

1.60 L of 10% solution

0.40 L of 35% solution

Step-by-step explanation:

If x = amount of 10% saline solution, and y = amount of 35% saline solution, then:

x + y = 2

0.10x + 0.35y = 0.15(2)

Solve with substitution:

0.10x + 0.35(2 − x) = 0.15(2)

0.10x + 0.70 − 0.35x = 0.30

0.40 = 0.25x

x = 1.60

y = 0.40
