Answer:
C
Step-by-step explanation:
The area (A) of a circle is calculated as
A = πr² ( where r is the radius )
Here diameter = 8 cm , thus r = 8 ÷ 2 = 4 cm , thus
A = π × 4² = 16π cm² → C
IF one side = a
Then the surface is <span> 6a^2</span>
Are you asking for the letter or what the line is called because if it's just the letter then it is r if it is the name then its a plane intersect.
