Answer:
1048.32 or 432 pi
Step-by-step explanation:
12*12=144
144+(4/3 pi *6^3)
6*6*6=216
216*4/3pi=864/3
864/3=288
288*3.14(pi)=904.32
904.32+144=1048.32
(If you have the pi symbol the answer is 144+288=432pi)

Answer:
b = 72
c = 36
d = 144
Step-by-step explanation:
As every angle in the pentagon are equal (the lines inside every angle mean they are equal), angles on a straight line must add up to 180° ∴
A = 108°
108 + b = 180
180 - 108 = b
72 = b
As the top left angle of the triangle is also on a straight line with one of these angles, the value of this angle is also 72°.
All angles in a triangle must add up to 180° ∴
72 + 72 + c = 180
144 + c = 180
c = 180 - 144
c = 36
Angles on a straight line must add to 180° ∴
d + c = 180
d + 36 = 180
d = 180 - 36
d = 144
