Devansh Arora 5 years, 4 months ago

if we cut a cylinder from one side heightwise we get a rectangle. So when you cut a cylinder the height changes to the length of the rectangle and circumference changes to the breath. So, 2πr= breathe 2×3.14×6= breathe 37.70 cm (approx.)= breathe h= length thus, 15 cm= length Take a rectangle of these dimensions and fold it length wise to get a cylinder of radius 6cm and height 15cm

Vikrant Dave 5 years, 4 months ago

√3 is the answer

0Thank You

Yogita Ingle 5 years, 4 months ago

Area of equilateral triangle = (√3/4) a²
Here side(a) = 2 cm
= (√3/4) (2)²
= (√3/4) x (2) x (2)
= (√3)
= √3 cm²
Therefore area of an equilateral triangle whose side is 2 cm is √3 cm²
