A-3,b-1

Yogita Ingle 6 years, 2 months ago

Given, x=a and y=b.
Given equations, x-y=2( assume it as equation 1)
x + y = 4( assume it as equation 2)

Equation 1+2,
x-y = 2
x+y = 4
- - - - - - -
2x = 6( y gets cancelled as there is a negative y and a positive y implies y-y=0)
x  = 6/2
x = 3
But x = a implies a =3
substitute a in equation 1 (it can be substituted even in equation 2)
x-y=2
3-y=2
y=3-2
y=1
But y=b implies b=1
Therefore, a=3 and b=1

Perimeter of semicircle= πr + 2r
perimeter is 36cm
36 = 22/7r + 2r
36 = 22r + 14r/7
36 = 36r/7
r = 36 × 7/36
r = 7
Diameter = 2 × 7
= 14

Total surface area = 216 cm²
Let the side of the cube = a 
Thus 6a² = 216
⇒ a² = 216/6
⇒ a² = 36
⇒ a = √36 
⇒ a = 6 cm

Volume = a³ cm³ = 6³ cm³ = 216 cm³

Aadya Singh ? 6 years, 2 months ago

It's volume is also 216cm^3..
