Answer:

64
$\pi$ mm² or approximately 201.06 mm²

Explanation:

If the diameter is 16 mm, the radius will be 8 mm.

Use the circle area formula, A =
$\pi$ r², where r is the radius. Plug in 8 as r:

A =
$\pi$ r²

A =
$\pi$ (8²)

A = 64
$\pi$

So, the area of the circle is 64
$\pi$ mm² or approximately 201.06 mm²

Question:-

If the diameter of the circle above is 16 mm, what is the area of the circle ?

Diameter of the circle = 16 mm. (Given)

Radius (r) of the circle = 16/2 = 8 mm.

$\bigstar$ To Find the area of the circle.

Since we know,

$\dag$ Area of circle is πr².

So, Area of the circle = 3.14 × (8)²

Area of the circle = 3.14 × 8 × 8

Area of the circle = 200.96 = 201 mm².
