Question

if the length of a diagonal of a cube is 6√3cm then it's surface area is 1)36cm 2)216cm 3)216cm 4)36cm MCQ HAI PLEASE BATA DO​

Answer 1

Step-by-step explanation:

H ^2=B ^2 +P ^2

Then given that

Distance between chord from radius =5 cm

Length of chord =24 cm

H ^2 =B ^2 +P ^2

H= 12 ^2 + 5^2

⇒H= 144+25

⇒H= 169

⇒H ^2 = (13) ^2

⇒H=13cm

∴ Radius of the circle =13 cm.

Diameter of the circle =2×radius=2×13=26cm.
