3a -8a + Z = -8+8
-5a = -Z
5a = Z
It is 108 degrees
4x+8=3x+33
X=25
3(25)+33=108 degrees
Answer:
surface area is 39
Step-by-step explanation:
add the areas of each geometric figure making up the composite 3D figure.
first 3D figure
2+2+6+6
=16---eq 1
from third 3D figure
4+4+10+5
= 23
from 1 and 2
16+23
= 39

Answer:
- area: 36π ≈ 113.1 . . . . square units
- circumference: 12π ≈ 37.7 . . . . units
Step-by-step explanation:
The area formula is ...
A = πr^2
A = π(6^2) = 36π ≈ 113.1 . . . . square units
__
The circumference formula is ...
C = πd
C = π(12) = 12π ≈ 37.7 . . . . units
