Answer 1

━━━━━━━☆☆━━━━━━━

▹ Answer

A ≈ 201.06 mm²

▹ Step-by-Step Explanation

A = πr²

Radius = 1/2d

Radius = 1/2(16)

Radius = 8

Substitute:

A = π8²

A ≈ 201.06 mm²

Answer 2

Answer:

The answer is 201 mm²

Step-by-step explanation:

Area of a circle is given by πr²

where r is the radius

To find the radius we use the formula

radius = diameter / 2

From the question

diameter = 16mm

radius = 16 / 2 = 8mm

So the area of the circle is

π(8)²

= 64π

= 201.061

= 201 mm² to the nearest whole number

Hope this helps you
