Answer:
The Number is 8.
Step-by-step explanation:
Let the number be x.
Given:
1/2 is subtracted from four times the reciprocal of a number, the result is 0.
Hence the equation will become like;

Now Solving the equation we get.

Now the we can see the number is 8, when 1/2 is subtracted from 4 times the reciprocal of number means 4/8 which becomes 1/2 and hence when 1/2 is subtracted from 1/2 it equals to 0.
Hence the number is 8.
we are given

for finding y , we can isolate y
so, we can divide both sides by 0.6

Step-by-step explanation:
d = 8 cm
r = 8 : 2
r = 4 cm
<h3>V = πr²h</h3>
= π × 4 × 4 × 18
