Answer:
15
Step-by-step explanation:
usually to find a percent of a number I convert the percent to decimal form and multiply that by the value.
Example: 50%=0.50
0.50*30=15
but since this is an easy one I just took half of 30 which if 15
hope this helps <3
.5 * 30 = 15
1: 3z+5
2: 50+20x
3: (15y+18)-4
4: 12a+8

=2π(17)(27)+2π(17)²
= 918π + 578π
=1496π
