Not sure what the correct description is but the answer is:
x <span>≥ 8</span>
5-12 ÷(6-2)-1
Do whats in the parenthesis
5-12 ÷4-1
Do division next
5- 3- 1 = 1.
Do the same for the next.
(4-3) x 2+15 ÷(6-1)
1 x 2+15 ÷5
2+15÷5
2+3= 5
For squrae
area=side²
perimiter=4(side)
for circle
area=pir²
circumference=2pir
side=diameter, diameter/2=radius=side/2
find area not covered
that is areasquare-areacircle
areasquare=26²=676 sqauare inches
areaciecle, diameter=side, 26/2=13, area=pi13²=169*3.14=530.66 square inches
areanotcovered=676-530.66=145.34 square inches not coverd
ratio of perimiter to circumferece
perimiter=4*26=104
circumference=2pir=2pi13=26pi=26*3.14=81.64
circumference to perimiter is 81.64/104=0.785
