  • Surface Area=7238in^2

We know

\boxed{\sf Surface\:area=4\pi r^2}

\\ \sf\longmapsto 4\pi r^2=7238

\\ \sf\longmapsto 4\times \dfrac{22}{7}r^2=7238

\\ \sf\longmapsto r^2=\dfrac{7238\times 7}{88}

\\ \sf\longmapsto r^2=\dfrac{5066}{88}

\\ \sf\longmapsto r^2=575.75

\\ \sf\longmapsto r^2\approx576

\\ \sf\longmapsto r\approx\sqrt{576}

\\ \sf\longmapsto r\approx24in

Please solve for x. I need this answered.
spin [16.1K]

2.5x - 3 + 2x = 1.75x - 1.25x + 13

4.5x - 3 = 0.50x + 13

4.0x = 16

x = 4

Answer: 4

2. We'll assume those xs are in the numerator

(3/7)x - 1/4 + (3/7)x = (9/7)x - (3/7)x + 3/4 - 1

(6/7)x - 1/4 = (6/7)x  - 1/4

0 = 0

That's always true.

Answer: Any x is a solution.
