Solving the area of the circle
A = π × 2^2
A = 12.57
halve
/2 = 6.29
area of the square = 4*4
16
subtract area of half circle from area of square
16 - 6.29 = 9.71
Answer:
in total only 2 triangles can fit in the box
Step-by-step explanation:
all u have to do is take the box length (10) and divide it by the triangle length (5) and you get 2
I feel like I just solved this one. its -1 isn't it?
We use equations for geometric sequence. We do as follows:<span>
a(n) = a(1) r^(n-1)
20 = ar^(2-1)
</span>20 = ar<span>
a = 20/r
11.25= ar^(4-1)
</span>11.25 = ar^3
<span>11.25 = (20/r)r^3
r = 0.75
Hope this answers the question. Have a nice day.</span>
