What is the best approximation for the circumference of a circle with a radius of 125 m?
ANEK [815]

Answer:

Option B is correct

circumference of a circle is 785 m

Step-by-step explanation:

Circumference of the circle(C) is given by:

C = 2\pi r

where

r is the radius of the circle

As per the statement:

radius of the circle is 125 m

then substitute in [1] we have

C = 2 \cdot 3.14 \cdot 125

Simplify:

C = 785 m

Therefore, the circumference of a circle is 785 m

If 5 ibs apples cost $2.99, how much would 3 ibs cost?
AnnZ [28]

We know that 5 lbs of apples cost $2.99

To know how much do 3 lbs of apple cost, you can use cross multiplication

If 5 lbs cost $2.99

Then 3 lbs cost $x

The proportion between the price and the number of apples is the same, you have to calculate it as:

\begin{gathered} \frac{2.99}{5}=\frac{x}{3} \\ (\frac{2.99}{5})\cdot3=x \\ x=1.794 \end{gathered}

3 lbs of apples cost $1.79
