I need help with this problem too
Answer:
A. 502.4 cm^3
Step-by-step explanation:
r=8/2=4 cm
V=pi*r^2*h=3.14*16*10=502.4 cm^3 (A)
Answer:
x = 3
Step-by-step explanation:
7/x - 3/(2x) + 7/6 = 9/x
x(7/x - 3/(2x) + 7/6) = x(9x)
x*7/x - 3*x/(2x) + x*7/6 = x*9x
7 - 3/2 + 7x/6 = 9
7x/6 = 9 - 7 + 3/2
7x/6 = 2 + 3/2
7x/6 = 12/6 + 9/6
7x = 12+9
7x = 21
x = 21/7
x = 3
probe:
7/3 - 3/(2*3) + 7/6 = 9/3
14/6 - 3/6 + 7/6 = 3
(14 - 3 + 7) / 6 = 3
18/6 = 3
It’s 500.07
all i did was solve x-7%=500 and got 500.07.
90 degrees
Hope this helps
