Answer:
82.4 ft^3
Step-by-step explanation:
Diameter=5.4ft
Radius=diameter/2
=5.4ft/2
=2.7ft
π=3.14
Volume of a sphere=4/3πr^3
=4/3×3.14×2.7^3
=4/3×3.14×19.683
=4/3×61.80462
=247.21848/3
=82.40616
Approximately
82.4 ft^3
Answer:
Step-by-step explanation:
7). (x + 3)(x + 7)
= x(x + 7) + 3(x + 7)
= x² + 7x + 3x + 21
= x² + 10x + 21
8). (4x + 2)(x - 2)
= 4x(x - 2) + 2(x - 2)
= 4x² - 8x + 2x - 4
= 4x² - 6x - 4
9). (3x + 2)(2x + 5)
= 3x(2x + 5) + 2(2x + 5)
= 6x² + 15x + 4x + 10
= 6x² + 19x + 10
10). (x² - 6)(x - 4)
= x²(x - 4) - 6(x - 4)
= x³ - 4x² - 6x + 24
11). (x² + 9)(x - 3)
= x²(x - 3) + 9(x - 3)
= x³ - 3x² + 9x - 27
12). (4x²- 4)(2x + 1)
= 4x²(2x + 1) - 4(2x + 1)
= 8x³ + 4x² - 8x - 4
Answer:
3
Step-by-step explanation:
Well percents are probability, and probability is similar to theory. So i think its theoritical probability.
Hope this helps.
