What is the approximate radius of a sphere with a volume of 113 cm3?O A. 3 cm O B. 4 cm O c. 2 cm O D. 5 cm

Vitek1552 [10]

Considering it's volume of 113 cm³, the approximate radius of the sphere is given by:

A. 3 cm

<h3>What is the volume of an sphere?</h3>

The volume of an sphere of radius r is given by:

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

In this problem, we have that V = 113 cm³, hence the radius in cm is given as follows:

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

$113 = \frac{4\pi r^3}{3}$

$r^3 = \frac{113 \times 3}{4\pi}$

$r = \sqrt[3]{\frac{113 \times 3}{4\pi}}$

r = 3 cm.

Hence option A is correct.

What is the solution of √1-3x=x+3

SOVA2 [1]

Answer:

x = -1

Step-by-step explanation:

$\sqrt{1-3x}=x+3\\\\1-3x=x^2+6x+9 \qquad\text{square both sides}\\\\x^2+9x+8=0 \qquad\text{put in standard form}\\\\(x+8)(x+1)=0 \qquad\text{factor}\\\\\left \{ {{x=-8} \atop {x=-1}} \right. \qquad\text{values that make the factors zero}$

Only the solution x = -1 will work for this equation. The other solution is extraneous.
