3.	Find the radius of base of a cone whose curved surface area is 1884.4 square meter and it's slant height is 12 cm.Answer is approx 5 cm
Answer» Question⇒ find the RADIUS of base of a cone whose curved surface AREA is 1884.4 square meter and it's SLANT height is 12 cm. Step-by-step explanation: given the slant height of the cone is 12cm = CSA of the cone = 1884.4m² = 18844000cm² we KNOW the formula for the CSA of the cone, that is πrl where r is the radius of the base of the cone and l is the slant height of the cone. therefore πrl = 18844000cm² >> 22/7 × r × 12 = 18844000m² >> 12 × r = 18844000/1 × 7/22 >> 12 × r = 5995818.18 >> r = 5995818.18/12 >> r = 499651.515 cm hence, the radius of the cylinder is 499651.515 cm. Answer is approx 5 cm

Find the radius of base of a cone whose curved surface area is 1884.4 square meter and it's slant height is 12 cm.Answer is approx 5 cm

Answer»

Question⇒ find the RADIUS of base of a cone whose curved surface AREA is 1884.4 square meter and it's SLANT height is 12 cm.

Step-by-step explanation:

given the slant height of the cone is 12cm =
CSA of the cone = 1884.4m² = 18844000cm²
we KNOW the formula for the CSA of the cone, that is πrl where r is the radius of the base of the cone and l is the slant height of the cone.

therefore πrl = 18844000cm²
>> 22/7 × r × 12 = 18844000m²
>> 12 × r = 18844000/1 × 7/22
>> 12 × r = 5995818.18
>> r = 5995818.18/12
>> r = 499651.515 cm
hence, the radius of the cylinder is 499651.515 cm.

Answer is approx 5 cm

ANSWER:

$55c+13\le \:75c+39\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:c\ge \:-\dfrac{13}{10}\:\\ \:\mathrm{Decimal:}&\:c\ge \:-1.3\\ \:\mathrm{Interval\:Notation:}&\:[-\dfrac{13}{10},\:\infty \:)\end{bmatrix}$

Step-by-step EXPLANATION:

$55c+13\le \:75c+39$

$\gray{\mathrm{Subtract\:}13\mathrm{\:from\:both\:sides}}$

$55c+13-13\le \:75c+39-13$

$\gray{\mathrm{Simplify}}$

$55c\le \:75c+26$

$\gray{\mathrm{Subtract\:}75c\mathrm{\:from\:both\:sides}}$

$55c-75c\le \:75c+26-75c$

$\gray{\mathrm{Simplify}}$

$-20c\le \:26$

$\gray{\mathrm{Multiply\:both\:sides\:by\:-1\:\left(reverse\:the\:inequality\right)}}$

$\left(-20c\right)\left(-1\right)\ge \:26\left(-1\right)$

$\gray{\mathrm{Simplify}}$

$20c\ge \:-26$

$\gray{\mathrm{Divide\:both\:sides\:by\:}20}$

$\dfrac{20c}{20}\ge \dfrac{-26}{20}$

$\gray{\mathrm{Simplify}}$

$c\ge \:-\dfrac{13}{10}$

Answer» ANSWER: 51 Step-by-step EXPLANATION: let the two consecutive numbers be 'x' and 'x+1' their SUM equal to 101 x + x + 1 = 101 2x + 1 = 101 2x = 101 - 1 2x = 100 x = 100/2 x = 50 the GREATEST number = x + 1 = 50 + 1 = 51

10.

If the sum of two consecutive numbersis 101, then find the greater one.

Answer»

ANSWER:

51

Step-by-step EXPLANATION:

let the two consecutive numbers be 'x' and 'x+1'

their SUM equal to 101

x + x + 1 = 101

2x + 1 = 101

2x = 101 - 1

2x = 100

x = 100/2

x = 50

the GREATEST number = x + 1 = 50 + 1 = 51

Answer» Answer: 8, 24 years Step-by-step EXPLANATION: Let age of Sita = X years. Then, Age of REENA = 32 - x years Also, Age of reena is 3 times age of sita. Thus, $(32 - x) = 3x\\\\\\\implies 32 - x - 3x = 0\\\\\\\implies - 4x = - 32\\\\\\\implies x = 8 \: years$ HENCE, age of Sita = 8 years and of reena = 32-8 = 24 years. Also, Reena's age os 3 times that of sita as 8*3 = 24.

Answer»

Answer:

8, 24 years

Step-by-step EXPLANATION:

Let age of Sita = X years.

Then, Age of REENA = 32 - x years

Also, Age of reena is 3 times age of sita.

Thus,

$(32 - x) = 3x\\\\\\\implies 32 - x - 3x = 0\\\\\\\implies - 4x = - 32\\\\\\\implies x = 8 \: years$

HENCE, age of Sita = 8 years and of reena = 32-8 = 24 years.

Also, Reena's age os 3 times that of sita as 8*3 = 24.

The sum of squares of 3 nos. Are in ratio 2:3:4 is 725. What are the numbers

Answer»

Answer:

Step-by-step explanation:

Let the COMMON RATIO of numbers be x

Then the numbers are 2x,3x and 4x

As per question .

(2x)^2 + (3x)^ +(4x)^2 = 725

4x^2 +9x^2 +16x^2 = 725

29x^2 =725

x^2 =725/29

x ^2 = 25

x = √25 =5

Hence the numbers are

2x = 2×5 = 10

3x = 3 × 5 = 15

4x ,=4 × 4 = 20

Hope it is clear.
