Answer:D
Step-by-step explanation: trust me ima sophomore use this for help y=1/2x+4 then x value change it to the number in the x section then if the y appears just like in the box the y section it’s correct
Ok so 1inch=40cm
2 inches by 1.5
multiply everybody by 40 and make them all centimeters
20*2=80
1.5*40=60
80cm by 60cm
1inch=2.54cm
find how many inches in 1 cm
divide both sides by 2.54
1/2.54inch=1cm
80 by 60 cm
multiply that by 1/2.54 nd find inches iquivlent
80 times 1/2.54=31.4960629921259842519685037008
60 times 1/2.54=23.622047...
ok so
dimentions is 31.4960629921259842519685037008 inches by 23.622047 inches
Plugging directly into the combination formula, the answer is 
where we have cancelled out common factors.
● Answer:
8.995 cm
● Step-by-step explanation:
P = d + L/2
d = 3.5 cm
L/2 = 2pi×r/2
= pi×d/2
= 3.14×3.5/2
= 5.495 cm
P = 3.5cm + 5.495
= 8.995 cm
