Answer:

C. Not given

V≈ 113 in³

Step-by-step explanation:

The volume of a sphere can be found using the following formula.

V= \frac{4}{3} \pi r^3

We know the radius is 3 inches and we are using 3.14 for pi. Therefore, we can substitute 3 in in for r and 3.14 in for \pi

V= \frac{4}{3} *3.14* (3 in)^3

Evaluate the exponent first.

(3 in)³=  3 in * 3 in * 3 in = 9 in² * 3 in = 27 in³

V= \frac{4}{3} *3.14* 27 in^3

Multiply 3.14 and 27 in³

V= \frac{4}{3} * 84.78 in^3

Multiply 4/3 and 84.78 in³

V= 113.04 in^3

Round to the nearest cubic inch. The 0 in the tenth place tells us to leave the 113 as is.

V= \approx 113 in^3

Since 113 cubic inches is not an answer choice given, the correct answer is C. not given

Answer: C. not given

Step-by-step explanation:

formula for volume of sphere: V=(4/3)πr³

V=(4/3)πr³

V=(4/3)(3.14)(3)³

V=(4/3)(3.14)(27)

V=113 in³

Complete the equation to represent finding x, the greater integer.<br><br> x(x – ) = 143
mart [117]

Answer:

x would equal -11 or 13

Step-by-step Explanation:

x(x - 2) - 143 = 0

x^2 - 2x - 143 = 0

-2x + x^2 = 143

-143 + (-2x) + x^2 = 0

(x - 13)(x + 11)

x - 13 = 0

Add 13 to both sides

x = 13

x + 11 = 0

Subtract 11 from both sides

x = -11
