3. The total surface area of a cylinder of radius 7 cm is 880 m^2 . Find the height.

Answer»

Answer ....

Total surface AREA = 880

2.22/7.7.h + 2 . 22 / 7 . 7. 7 = 880

44.h + 308 = 880

44. h = 572

h = 572/ 44

h = 13 cm

volume = 22/7 .7.7.13

volume = 2002 CM3

12657.

The sum of the digits of a two-digit number is 15. On subtracting 27 from the given number its digits get reversed. Find the given number.

Answer»

$\large\bf\underline {To \: find:-}$

We need to find the number.

$\huge\bf\underline{Solution:-}$

$\bf\underline{\red{Given:-}}$

● Sum of DIGITS = 15
● if we subtract 27 from the original number then the digits gets reversed.

Let :-

Units place DIGIT be x and ten's place digit be y.

Number formed = 10x + y

➳ Sum of digits = 15

➳ x + y = 15

➳ x = 15 - y ......1)

☘️According to Question :-

On subtracting 27 from the given number its digits get reversed.

➛ (10x + y) - 27 = 10y + x

➛ 10x - x - 10y + y = 27

➛ 9x - 9Y = 27

▶Dividing both sides by 9 we get,

➛ x - y = 3

⪼ From equation 1)

➛ 15 - y - y = 3

➛ 15 - 2y = 3

➛ - 2y = 3 - 15

➛ - 2y = -12

➛ y = 12/2

➛ y = 6

▶ putting VALUE of y = 6 in Equation 1)

➻ x = 15 - y

➻ x = 15 - 6

➻ x = 9

✝️ Original number :-

10x + y
10 × 9 + 6
90 + 6
96

Hence,

༒ Original Number is 96
