Answer:
37 books
Step-by-step explanation:
radius* 2=diameter so no diameter and radius aren't the same thing because radius is half the distance across the circle and diameter is the full distance across the circle.
Answer:
4Z+16-Z²
Step-by-step explanation:
Given that,
D = Z+6
C = -2 + Z - Z²
We need to find the value of 3D+C.
So,
3D+C = 3(Z + 6)+(-2 + Z - Z²)
= 3Z+18-2+Z-Z²
= 4Z+16-Z²
So, the required expression is 4Z+16-Z².
