32 square root 6
use the pythagoream theorum
the sides would be 32 and 16. 16^2+x^2=32^2
Answer:
The person above is correct
Step-by-step explanation:
Answer:
Step-by-step explanation:
Diameter = 8 yards so the Radius = 4 yards:
Area of a sphere = 4π.R² and hemisphere = 2π.R²
Area of hemisphere = 2.π.(4)² = 32.π
But note we didn't calculate yet the are that closes this hemisphere:
Area of the cicle = π.R² = π.(4)² = 16.π, so the surface area of the hemisphere is 32π + 16π = 48.π (Or =150.8 yard²)
Answer:
x³ -x²-30x+72
Step-by-step explanation:
→ ( x - 3 ) ( x - 4 ) ( x + 6 )
[ expand and open brackets ]
→ ( x² -4x -3x + 12 ) ( x + 6 )
[ simplify ]
→ ( x² -7x + 12 ) ( x + 6 )
[ expand ]
→ x³ +6x² -7x² - 42x + 12x + 72
[ simplify/ final answer ]
→ x³ -x² -30x +72
