Answer:

Step-by-step explanation:

a) circumference = diameter*pi

so, pi in circle A =25.12/8=3.14

pi in circle B = 9.42/3 =3.14

b) area of the circle =(diameter/2)^2*pi

so pi in circle A = 50.24/(8/2)^2=3.14

pi in circle B = 3.14

A pharmacist is filling small empty bottles with cough syrup from a larger bottle. He can solve the inequality to find the numbe
andrey2020 [161]

Let us assume capacity of large bottle = 1000 ml.

And capacity of each small bottle = 25 ml.

Reaming milliliters in large bottle = 250 milliliters.

Number of bottles = x bottles.

Total capacity of large bottle - capacity of a small bottle × number of bottles > Reamining milliliters in large bottle.

Therefore, we can setup an inequality.

1000 - 25 × x > 250.

1000 -25x >250.
