Answer:
i am sorry if it is wrong my answer is 1,536
Step-by-step explanation:
so if i am correct 8cm³ the formula for a surface area of a cube is:
SA=s³
Well using mental math, subtract .04 from 1.6 to get 1.56, which is s
The legnth is irrelivant
we know that
Circumference=2 times pi time radius
c=40
40=2 times pi times radius
divide both sides by 2
20=pi times radius
divide both sides b pi
20/pi=radius
the radius is 20/pi cm or aproximately 6.366199048 cm
you can work it out or put in random numbers until the two sides are equal
Answer:
1. 9x-8y=9
2. -18x+16y= -18 ⇒ -9x+8y= -9 ⇒ 9x-8y=9
as we see both equations are same, it means the lines overlap and there is infinite number of solutions
