Isolate the variable by dividing each side by factors that don't contain the variable.
Answer:
6km
Step-by-step explanation:
Area of circle = πr²
Where r = radius, π= 3.14, A = 28.26km²
A = 3.14 x r²
3.14 r2 = 28.26
Divide both sides by 3.14
r²= 28.26/3.14
r² = 9
Square root both sides
r= √9
r= 3
Radius = 3km
Note : Diameter = 2 x radius
Diameter = 3 x 2
Diameter = 6km

Answer:
253.548 minutes which rounds to 254 minutes
Step-by-step explanation:
1 hour = 60 minutes

253.548 minutes
The question does not specify how to round it so I will round to the nearest whole number: 254 minutes.
