Answer:
B, 25.9 pi
Step-by-step explanation:
360 - 170 = 190
r= 7
pi 7^2 = 49 pi
49/2 = 24.5 pi
24.5 + 1.4 = 25.9 pi
Answer:
s = -7.8
Step-by-step explanation:
from the question 12=10(s+4)+50
<u>first step</u>
open the bracket and evaluate for the value of s
12=10(s+4)+50
12 = 10s + 40 + 50
12 = 10s + 90
collect or combine the like terms
12-90 = 10s
-78 = 10s
divide both side by 10
-78/10 = 10s/10
-7.8 = s
therefor s = -7.8
