Answer:
90π units²
Step-by-step explanation:
(refer to attached)
Total Surface are off a right cylinder = area of its ends + area of curved surface
Given radius, r = 3 units and height, h = 12 units
Area of 2 ends,
= Area of 2 circles
= 2 x πr²
= 2π (3²)
= 2π (9)
=18π units²
Area of curved surface,
= 2πrh
= 2π(3)(12)
= 72π units²
Hence,
Surface area = 18π + 72π = 90π units²
The one year savings of Mr. Nadir is $. 34, 425
Given:
Mr. Nadir Monthly salary = $6723.50
His monthly Expenditure = $3854.75
Now we have to find the savings amount of each month.
For that, first we have to calculate the remaining amount he has after spending the expenditure.
To calculate the remaining amount we have to subtract the expenditure from the total amount that's is his salary.
So,
Remaining amount = Salary - Expenditure
Remaining amount = 6723.50 - 3854.75
=> 2868.75
So, for one year he must save the amount
=> 2868.75 x 12 = 34425
