Question

234.51ha change to m

Answer 1

Ha is used to quantify area. m is used to quantify distances. I think u typed wrongly? It should be m^2 or square meters.

Anw 1 ha is equivalent to 10 000 square meters.

So just multiply to get the answer.

Answer 2

calculate the circumference,area and radius of the circle

Answer 3

I assume the striaght line u draw in the circle is 9cm. That is the diameter.

Given diameter, the radius is 9/2= 4.5cm (note diameter is 2 times of radius)

Circumference is given by formula= 2*pi*r (note r stands for radius)
= 2*pi*4.5
=28.3cm

Area of circle is given by formula = pi*r^2
= pi* 4.5^2
=63.6 cm^2
