The formula to find the area of a circle is:
[tex]a= \pi r^{2} [/tex]
Step 1:We will be dividing the diameter by two to find the radius.
16 ÷ 2 = 8
Step 2:We will find what 8 squared is.
[tex] 8^{2} [/tex]
8*8= 64
Step 3:We will be inputting this number is our formula.
[tex]A= \pi 64 [/tex]
Step 4:We still need to multiply [tex]64 * \pi [/tex] to find our area.
[tex]64 * \pi [/tex] = 201.0619298297467673
Step 5:
We will round this to the nearest whole number.
Our rounded number is 201
Our answer:
[tex]\boxed{a=201}[/tex] or [tex]\boxed{a=201.06}[/tex]
