250/360 = x/60
x = 41.7 cm
This is because when the whole circle is 250 cm (angle is 360 degrees), 60 degrees means that the arc is 41.7 cm.
All of the start out with one and then add 2 from there and they add a block on top
The answer is 864 cubic meters
12.
12cm already and in 12 week it will grow 12cm more so total 24cm in week
On other hand the seed will grow 2cm per week so in 12 week it will be 24 cm
Circle geometry rule: Tangent to circle makes right angle with the radius
Please refer to the diagram below for the working out of each angle
