Answer:
24x+3
Step-by-step explanation:
Answer:
Following the rule of BIDMAS
we will solve the one inside the bracket first, Addition will be solved before subtraction
i.e ( 5+4-2) x ( - 2)
= ( 9-2) x (-2)
= 7 x -2
= - 14
Step-by-step explanation:
Answer:
y=-2x-1
Step-by-step explanation:
Answer:
654 1/2 cm³
Step-by-step explanation:
First the volume of the cylinder, the formula for that is πr²h
Radius is half of diameter so 7/2=3.5
3.5^2=12.25
12.25x22/7=38.5
38.5x15=577.5
Now the cone, the formula for this is πr²h/3
It has the same radius as the cylinder so 3.5^2=12.25
12.25x22/7=38.5
38.5x6=231
231/3=77
Now we add them together to find total volume.
577.5+77=654.5
