8n + 3= 11n
11n-4=7n
+4n=11n
The answer is C: first add 2 both sides then divide both sides by -5.
Answer:
17.4 ina
Step-by-step explanation:
Area of circle = πr²
Where r = radius, π = 3.142 , A = 240.251 ina
A = 3.142 x r²
3.142 r² = 240.251
Divide both sides by 3.142
r² = 240.251/3.142
r² = 76.464
Square root both sides
r= √76.464
r= 8.7
Radius = 8.7 ina
Note : Diameter = 2 x radius
Diameter = 8.7 x 2
Diameter = 17.4 ina
