Answer:

using pythagoras theorem

Step-by-step explanation:

lets assume h = 4

now,

$h^{2} = p^{2} + b^{2} \\4^2 = 2^2 + (2\sqrt{3})^2\\ 16 = 4 +12\\16 = 16$

hence they are the sides of a right angled triangle

The circumference of a flower garden is 247 ud. What is the area of the flower garden in terms of

lisov135 [29]

Answer:15252.25π^3

Step-by-step explanation:

Radius=r

Circumference=247 ud

Circumference=2 x π x r

247=2πr

Divide both sides by 2π

247/2π=2πr/2π

123.5π=r

Radius=123.5π

Area of circle=π x r x r

Area of circle=π x 123.5π x 123.5π

Area of circle=15252.25π^3
