Answer» Answer: PLSS FOLLOW me. Step-by-step EXPLANATION: let the radius of the cone , r = 10.5/2cm and slant height , l= 10cm *C.S.A of cone = πrl* = 22/7 × 10.5×10 cm² = 22 × 15 cm² = 330 cm² therefore , the c.s.a. of cone is 330cm². I hope this will help you and PLEASE FOLLOW ME.

2.

The diameter of the base of a cone is 10.5 cm, and its slant height is 10 cm. The curved surface area is:

Answer»

Answer:

PLSS FOLLOW me.

Step-by-step EXPLANATION:

let the radius of the cone , r = 10.5/2cm

and slant height , l= 10cm

C.S.A of cone = πrl

= 22/7 × 10.5×10 cm²

= 22 × 15 cm²

= 330 cm²

therefore , the c.s.a. of cone is 330cm².

I hope this will help you and PLEASE FOLLOW ME.

7.	How many days will 1300 men take to dig trench, if 625 men can do the same in 52 days
Answer» For this one our output is 'trenches' and our inputs are men and days. EXPRESSING the example algebraically we have 6 trenches = 3 men times four days. 6t = 3m x 4d To generalise the input for one TRENCH, we need to CREATE a hybid unit, the 'manday'. The number of mandays is the product of its inputs. So: 6t = 12 mandays Solving for one trench gets us: t = 2 md. We can use this to solve the problem, how many days for 4 men to do 24 trenches. 24t = 48md. We can find the number of days by dividing by our KNOWN number of men. 48 md / 4 men = 12 days.

How many days will 1300 men take to dig trench, if 625 men can do the same in 52 days

Answer»

For this one our output is 'trenches' and our inputs are men and days. EXPRESSING the example algebraically we have 6 trenches = 3 men times four days.

6t = 3m x 4d

To generalise the input for one TRENCH, we need to CREATE a hybid unit, the 'manday'. The number of mandays is the product of its inputs. So:

6t = 12 mandays

Solving for one trench gets us:

t = 2 md.

We can use this to solve the problem, how many days for 4 men to do 24 trenches.

24t = 48md.

We can find the number of days by dividing by our KNOWN number of men.

48 md / 4 men = 12 days.

A ball is thrown up with a speed of 0.5 m/s.(i) How high will it go before it begins to fall?

Answer»

Answer:

0.0012M

Step-by-step explanation:

SOLUTION:

DATA:

velocity=0.5m/s

final velocity=0

acceleration DUE to gravity=g= -9.8m/ $s^{2$ (it is TAKEN -ve as BODY moves against the gravity)

h=??

Formula:

2gH=V $f^{2}$ -V $i^{2}$

CALCULATION:

2(-9.8)H=(0)^2-(0.5)^2

-19.6H=0-0.25

H= -0.25/-19.6

H=0.0012m

RESULT:

IT WILL FALL FOR 0.0012METER.

the side of a triangle are in the ratio 2:3:4 if the perimeter of the triangle is 120 cm find the side . what know of the triangle is?

Answer»

${\huge{\underline{\underline{\rm{Question:}}}}}$

★ The sides of a triangle are in the ratio 2:3:4 . If the perimeter of the triangle is 120 cm , FIND the sides of the triangle .

${\huge{\underline{\underline{\rm{Answer\checkmark}}}}}$

★ GIVEN :

The ratio of sides = 2:3:4
Perimeter = 120 cm

★ To Find :

The sides of the triangle .

★ SOLUTION :

Let the ratios be 2x , 3x and 4x

That is ,

1st side = 2x
2nd side = 3x
3rd side = 4x

As we know ,

$\star \boxed{ \sf \: perimeter_{triangle} = 120 \: cm}$

Here ,

$\rm \mapsto \: 1st \: side + 2nd \: side + 3rd \: side = 120cm$

$\mapsto \rm \: 2x + 3x + 4x = 120 \: cm$

$\mapsto \rm \: \cancel{9}x = \cancel{120} \: cm$

$\mapsto \rm \: 3x = 40 \: cm$

$\mapsto \boxed{\rm x = \dfrac{40}{3} \: cm}$

So , Sides are :

$\sf \: 1st \: side \: = 2x = 2 \times \dfrac{40}{3} = \boxed{ \sf\dfrac{80}{3} \: cm}$
$\sf \: 2nd \: side = 3x = 3 \times \dfrac{40}{3} = \boxed{ \dfrac{120}{3} \sf\: cm}$
$\sf \: 3rd \: side = 4x =4 \times \frac{40}{3} = \boxed{ \sf \frac{160}{3} \: cm} \\$

Since all the sides are DIFFERENT in LENGTH ,

So,

It's a Scalene Triangle .

The sum of 10 terms of the GP 2, 4, 8, 16, 32 is

Answer»

Answer:

1022 is the sum of these 10 terms of GP.

Step-by-step explanation:

given:-

In GP,

first TERM(a) = 2

common ratio(r) = 4/2 = 2

since r>1

Sum of n terms(Sn) = a(r^(n-1)-1)

(r-1)

=> Sum = 2(2^(10-1)-1) = 2(2⁹-1)

2-1 1

=> Sum = 2(512-1)

=> Sum = 2×511 = 1022
