Answer 1

so the circumference of a circle is C=2 times pi times the radius. in this case it would be C= 2(pi)(4) which is 25.1 :)

Answer 2

Problem:-

Find the perimeter or circumference and area of each figure. Round to the nearest tenth.

Solution:-

The circumference of a circle with radius r is given by C = 2πr. The radius of the circle is 4 in.

Substitute 4 for r.

$\sf{C=2πr}$

$\sf{ \: \: \: \: =2π(4)}$

$\sf{ \: \: \: \: ≈{\color{darkviolet}{25.1}}}$

Answer:-

The circumference of the circle is about 25.1 in.

======================

The area of a circle with radius r is given by A = πr².

Substitute 4 for r.

$\sf{A = πr²}$

$\sf{ \: \: \: \: = π(4)²}$

$\sf{ \: \: \: \: ≈{\color{magenta}{50.3}}}$

Answer:-

The area of the circle is about 50.3 in².
