Circle a: π×r1^2=π×3^2=π×9. r1=3
Circle b: π×r2^2
(π×9)×25=π×r2^2. ( 25 Times circle a equals one time circle b)
9×25=r2^2
r2=√9×25= √225=15
Answer:
Has two unkown variables
Step-by-step explanation:
When there is only one equation provided with two unknown variables, it is difficult to solve for the unknown variables
The most simplified version of this equation would be VX = -14
More information would be needed to solve
Area of circle = pi r^2 = 78.54
r^2 = 78.54 / pi = 25
r = 5 inches
Each line from centre of the circle to a point on the hexagon = 5 ins
so consider one of the 6 congruent triangles formed from these lines:-
Vertex angle = 60 degrees
sin 30 = 0.5s / 5 (where s = one side of the hexagon).
0.5s = 5*0.5 = 2.5
s = 2.5 / 0.5 = 5
So the perimeter of the hexagon is 6*5 = 30 inches

Answer:
The answer to your question is: three hours.
Step-by-step explanation:
data
Jogger 1 = 6 mi/h
Jogger 2 = 6.5 miles/h , starts 15 min (0.25 h) after the first Jogger
Time when the second jogger catch the first jogger = ?
Process
Advantage of the first jogger d = vt = 6(0.25) = 1.5 mi
Distance where they meet 1.5 + 6t = 6.5t
Find the t value 6.5t - 6t = 1.5
0.5 t = 1.5
t = 1.5 / 0.5
t = 3 hours
