Answer:
5:7
Step-by-step explanation:
Let the radius of first hemisphere be 'r' units
Let the radius of second hemisphere be 'R' units
2 x \piπ x r^2 / 2 x \piπ x R^2 = 25 / 49
r^2 / R^2 = 25 / 49
r / R = 5 / 7
the ratio of radii is 5:7.
Answer:
39
Step-by-step explanation:
Let the number be x.
The quotient of x and 3 is 13.
x/3 = 13
Multiply both sides by 3.
x = 13 × 3
x = 39
