Answer:
A. 10cm
B. 8 times
Step-by-step explanation:
The question is on volume of a conical container
Volume of a cone= 
where r is the radius of base and h is the height of the cone
Given diameter= 12 cm, thus radius r=12/2 =6 cm

h=10 cm
B.
If height and diameter were doubled
New height = 2×10 =20 cm
New diameter = 2×12 = 24, r=12 cm
volume = 
To find the number of times we divide new volume with the old volume

The team won 4 gold medals, 4 silver medals and 10 bronze medals.
Step-by-step explanation:
Given,
Total medals won = 18
Ratio of gold, silver and bronze = 2:2:5
Let,
x be the original number.
Therefore,
Gold medals = 2x
Silver medals = 2x
Bronze medals = 5x
According to given statement;

Dividing both sides by 9

Gold medals = 2x = 2(2) = 4
Silver medals = 2x = 2(2) = 4
Bronze medals = 5x = 5(2) = 10
The team won 4 gold medals, 4 silver medals and 10 bronze medals.
