Answer:
£30
Step-by-step explanation:
To tackle these 'sharing' ratios problems, first find the total amount parts in the ratio.
1 : 6 = 1 + 6 = 7 parts
Now divide the total amount of parts by the total amount of money shared
35 / 7 = 5
Now multiply the answer by the value that is appropriate.
In this case, they want you to work out how much Ali recieved.
Ali's value is 6
6 × 5 = £30
hope this helps :)
Answer:
54461.33 cubic feet
Step-by-step explanation:
Given data
Height of cylinder= 40 feet
Radius= 20feet
Height of cone= 10 feet
Radius of cone= 20feet
Volume of Cylinder= πr^2h
Volume of Cylinder= 3.142*20^2*40
Volume of Cylinder= 3.142*400*40
Volume of Cylinder= 50272 cubic feet
Volume of Cone= 1/3πr^2h
Volume of Cylinder= 1/3*3.142*20^2*10
Volume of Cylinder= 1/3*3.142*400*10
Volume of Cylinder= 1/3*12568
Volume of Cylinder=4189.33 cubic feet
Hence, the volume of the silo = volume of cylinder+ volume of cone
Volume of silo= 50272+4189.33
Volume of silo=54461.33 cubic feet
13% = 13/100 = 0.13
3/25 = 0.12
0.13 > 0.12
So 13% is bigger than 3/25
