Answer:
...
Step-by-step explanation:
We need the radius to find the surface area. Since we have the circumference we can use that to find the radius.
C = 2πr
23 = 2(3.14)r
23 = 6.28r
23/6.28 = r
3.66 = r
Now use the radius to find the surface area.
SA = 4πr²
SA = 4(3.14)(3.66)²
SA = 168.33
Surface area is C. 168 cm²
Hope this helps :)
Answer:
391
Step-by-step explanation:
(23 x 10) + (23 x 7) =

250x⁴ + 128x
2x(125x³) + 2x(64)
2x(125x³ + 64)
2x(125x³ + 100x² - 100x² + 80x - 80x - 64)
2x(125x³ + 100x² + 80x - 100x² - 80x - 64)
2x(5x(25x²) + 5x(20x) + 5x(16) - 4(25x²) - 4(20x) - 4(16))
2x(5x(25x² + 20x + 16) - 4(25x² + 20x + 16))
2x(5x - 4)(25x² + 20x + 16)
