Answer:

1256 ft^2

Step-by-step explanation:

Area (A) of a circumference is A = π*r^2, where r is the radius of the circumference.

Taking into account that r = D/2, where D is the diameter of the circumference, therefore, the area formula can be written as

A = π*r^2

A = π*(D/2)^2

π*(D^2)/4

For this exercise, the diameter is 40 feet, hence

A = π*(D^2)/4 = 3.14*(40^2)/4 = 1256 ft^2

The local water slides have 100 employees, of which 30% are temporary. How many temporary employees are there?
Ugo [173]

Answer:

There are 30 temporary employees

Step-by-step explanation:

<em>To find </em><em>x% of quantity A</em><em>, multiply x% by A after change x% to the normal number by divide it by 100 ⇒ </em><em>(x ÷ 100) × A</em>

Let us use this rule to solve the question

∵ The local water slides have 100 employees

∵ 30% of them are temporary

∴ The number of temporary employees = 30% × 100

∵ 30% = 30 ÷ 100 = 0.30

∴ The number of temporary employees = 0.30 × 100

∴ The number of temporary employees = 30

∴ There are 30 temporary employees
