The student wrote the wrong operation. "The sum of 5y and 3" translates to 5y+3. And here means addition.
0.32. Because you need to find the area, as size 8*8/2 then divide by 100 to get the decimal.I hope this helps.
A = 180(n - 2)
a = 180n - 180*2
a = 180n - 360
180n - 360 = a
180n = a + 360
n = (a + 360) / 180
Numerator for fraction above = ( a + 360), denominator = 180
Area=pi times radiius^2
radius=diameter/2
diamter=5
radius=5/2=2.5
pi=3.14 aprox
area=3.14 times 2.5^2
area=3.14 times 6.25
area=19.625 ft^2
round
19.6 round up
20
the answer is 20 ft^2
2+-2 sq rt of 2 one of the answers you needed plz rate me
