PQ = PS
angle ∠RPS = ∠QPR
side PR is common in both
so by S.A.S criteria both triangles are congruent
and since both are congruent QR=SR

ANSWER
Let the cost of a notebook be Rs. x and that of a pen be Rs. y.
Given the cost of a notebook is twice the cost of a pen.
Then x = 2y
or, x − 2y = 0.
This is the required linear equation in two variable.

Since, The volume of a cylinder is,
Where r is the radius of the cylinder and h is the height.
Here, the diameter of one cylinder = 7 cm,
⇒ Radius of one cylinder, r = 7/2 = 3.5 cm
And, the height of a cylinder, h = 11 cm,
⇒ The volume of 1 cylinder,
⇒ The volume of 50 cylinder = 50 × 423.115
= 21,155.75 cube cm

{tex}(100+3)^2{/tex}
Using identity {tex}(a+b) ^2 =a^2 +b^2 +2ab{/tex}
{tex}=(100)^2 +(3)^2 +2×100×3{/tex}
= 10000+9+600
=10609

given
slant height = 2l
radius = 2r
total surface area of the cone = 2π*radius(radius+slant height)
=2π*2r[2r+2l]
= 4πr 2(r+l)
= 8πr (r +l) sq units

Slant height of the conical cup, 'l' = radius of the semi-circular sheet, R = 14 cm
Let radius and height of the conical cup be 'r' and 'h' respectively.
Circumference of the base of the cone = Length of arc of the semi-circle
Or, 2πr = (1/2)2πR
Or, 2πr = (1/2)(2π)(14)
Or, r = 7 cm
Now, we know that l² = h² + r²
(14)² = (h)² + (7)²
h² = 196 - 49
h = √147
Height or depth of the conical cup = 12.124 cm
Now, capacity of the conical cup = 1/3πr²h
= 1/3*22/7*7*7*12.124
= 13069.672/21
Capacity of the conical cup = 622.365 cu cm

Sorry, its the volume of cuboidal.
The surface area of cuboidal box = 2(lb + bh + lh)
Yogita Ingle 5 years, 1 month ago
T he surface area of cuboidal box = l × b × h
= 18cm × 16cm × 4cm

We know that, rational number is a number which can be written in the form of p/q , where q is not equal to zero.
<div>Thus, yes, zero is a rational number, as it can be written in the form of p/q. <div> </div> <div>Since, 0 (zero) is an integer thus, zero can be written in the form of p/q</div> <div> </div> <div>Example : 0/1, 0/2, 0/3, etc. where 0 (zero) is an integer..</div> </div>Posted by Hales Harriea 5 years, 1 month ago
