b
Step-by-step explanation:
I think its b I'm not sure but let me know if its wrong so I can improve
Step-by-step explanation:
3y + 10.5 = 6.5 + 2.5y
3y - 2.5y = 6.5 - 10.5
0.5y = - 4
y = 4 ÷ 0.5
y = 2
I think the answer is 126;
First you would have to multiply $18 (The cost for each month) and 12 (the number of months in a year) and the answer would be 216
So she deducts 216 a year, so the answer would have to be negative
The final answer is -216
The height of the right cone is 10.68 unit
<h3>What is Volume ?</h3>
Volume is defined as the space occupied by a three dimensional object.
Volume of a right cone is given by
V = π r²h/3
C = 2 π r
r = 247/2 π
3 * 17287 = π r²h
3 * 17287 = π *(247/2 π )²h
h = 51861 *π *4/61009
h = 10.68 unit
Therefore the height of the right cone is 10.68 unit.
