Answer:
574.85 in² (approx.)
Step-by-step explanation:
The sphere's volume equation is V = (4/3) * π * r³, which we can set equal to the given volume of 1296 in³:
1296 = (4/3) * π * r³
Now solve for r to get r ≈ 6.7635 in.
The surface area of a sphere is SA = 4 * π * r². Now substitute r into that equation to get:
SA = 4 * π * (6.7635)² ≈ 574.85 in²
I think you would multiply, so it would be 8x? So true..? I’m rlly sorry if you get it wrong
Well since 5% is .05 all you have to do is plug in the numbers so C=30.99+.05X(30.99) so the answer would be 32.5395
It would be C. isosceles triangle.

-6x+3y=9 -------(2)
(1) x 3 :
12x + 15y = 3 ------- (1a)
(2) x 2:
-12x + 6y = 18 ------ (2a)
(1a) + (2a):
15y + 6y = 3 + 18
21y = 21
y = 1 ------- sub into (1)
4x + 5(1) = 1
4x + 5 = 1
4x = 1 - 5
4x = -4
x = -1
Ans: x = -1, y = 1
