22cm^3
Step-by-step explanation:
My education system is different so I dont know what nearest tenth would mean in this .
But going mathematically:
Its diameter is 7 centimetres.
So to find its volume we can use the formula pi/d or pi/r^2
Now, 22/7÷7 would be 22cm³.
Answer:
A) 0.8
Step-by-step explanation:
0.8 on edge.
It will take 15 hours more to build the wall using only 5 bricklayers.
This question deals with indirect proportion. To solve it, you need to first find the product of the number of bricklayers and the number of hours it took to build the wall.
<em>= Number of bricklayers x Number of hours taken</em>
= 8 x 25
= 200 bricklayer hours are required to build that wall if using 8 bricklayers.
Because you are using 5 bricklayers, the number of hours they will take is:
<em>= Number of hours taken to build by 8 bricklayers/ Number of bricklayers available </em>
= 200 / 5
= 40 hours
Difference is:
= 40 - 25
= 15 hours
In conclusion, it will take 5 bricklayers, 15 hours more to build the wall.

We are given
Ronaldo delivers the papers at the rate of 6 papers in 24 minutes
so, number of papers =6 in time =24 minutes
so, firstly we can find rate
rate = ( number of papers)/( time taken)
now, we can find times
Time for 56 papers:
we are given
number of papers =56
rate is
now, we can find time
Time for 41 papers:
we are given
number of papers =41
rate is
now, we can find time
now, we can find time difference
so, we can plug values
