Answer:
.
Step-by-step explanation:
Let x represent the number.
We have been given a sentence. We are supposed to translate our given sentence into an inequality.
We are told that the number is at-least 90. This means that our required number is greater than on equal to 90.
We can represent this information in an inequality as:
Therefore, our required inequality would be .

Answer:
1774.67π mm³
Step-by-step explanation:
Please find attached to this question, the required diagram.
From the question, we are told we have a spherical mold.
We would find the volume of a spherical mold using the formula for the volume of a sphere.
The volume of a sphere is calculated as : 4/3πr³
From the attached diagram, we are given the Diameter do the spherical mold as: 22mm
Radius of the spherical mold = Diameter ÷ 2 = 22mm÷ 2 = 11mm
The volume of the spherical mold = 4/3 × π × 11³
= 1774.6666667π mm³
Approximately and leaving it in terms of pi (π)= 1774.67π mm³
