Answer:

Volume, $V=3052.08\ ft^3$

Step-by-step explanation:

It is given that,

Diameter of spherical boulder is 18 ft

Weight of spherical boulder is 8 tons.

We need to find the volume of spherical boulder. The formula of the volume of sphere is given by :

$V=\dfrac{4}{3}\pi r^3$

r is radius of spherical boulder, r = 9 ft

Substituting all values in above formula :

$V=\dfrac{4}{3}\times 3.14\times (9)^3\\\\V=3052.08\ ft^3$

The volume of spherical boulder is $3052.08\ ft^3$ .

What’s the correct why to solve

Vaselesa [24]

$x^2-y^2=2\\ \underline{x^2+y^2=4}\\\\ 2x^2=6\\ x^2=3\\ x=-\sqrt3 \vee x=\sqrt3\\\\ 3+y^2=4\\ y^2=1\\ y=-1 \vee y=1\\\\ x\in\{(-\sqrt3,-1),(-\sqrt3,1),(\sqrt3,-1),(\sqrt3,1)\}$

So, there are 4 solutions.

1. Both are corresponding angles, hence they both are equal, so,

$44x + 2 = 45x \\ = > 2 = 45x - 44x \\ = > 2 = x \\ = > x = 2$

Ans. C) 2

2. They both are in interior corressponding, hence their sum is equal to 180°, so,

$10x + 6 + 104 = 180 \\ = > 10x + 110 = 180 \\ = > 10x = 180 - 110 \\ = > 10x = 70 \\ = > x = \frac{70}{10} \\ = > x = 7$

Ans. D) 7

3. They both are in interior corressponding, hence their sum is equal to 180°, so,

$x + 75 + x + 125 = 180 \\ = > 2x + 200 = 180 \\ = > 2x = 180 - 200 \\ = > 2 x = - 20 \\ = > x = \frac{ - 20}{2} \\ = > x = - 10$

Ans. A) -10

4. Both are corresponding angles, hence they both are equal, so,

$12x + 3 = 11x + 9 \\ = > 12x - 11x = 9 - 3 \\ = > x = 6$

Ans. A) 6
