Question

find the height of an equilateral triangle whose area is equal to the area of a circle with circumference a 10cm

Answer 1

Apple pI r squared
( so )
A=nr^2 (where n is pI) (A is Area) (r is radius)
( and )
Chicken pI dinner
( so )
C = nd (where n is pI) (C is Circumferance) (D is diameter (2xr))

Answer 2

10= 3.14... x D
D/2 = R
Area = 3.14... x R^2
Area = Equilateral - from there i dunno
