A sphere has a radius of 5 inches. What is its volume?

jarptica [38.1K]

Given ↓

Radius of sphere = 5 in

The volume of the sphere

<h3>Calculations ↓</h3>

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

↑ formula for volume of a sphere

r = 5 in

Plug in the value of r and solve :

$\blue{\boxed{\mathsf{V=\frac{4}{3}\pi (5)^3}}}$

Simplify as follows :

$\blue{\boxed{\mathsf{V=\frac{4}{3}\pi *125} }}$

$\blue{\boxed{V=\frac{4}{3} *392.7}}$

Final Step :

$\blue{\boxed{\pmb{V=523.6\:in\:^3}}$

The equation of a circle is given below.

sergeinik [125]

Answer:

Center is $(-12,9)$

Step-by-step explanation:

Given: Equation of a circle is $(x+12)^2+(y-9)^2=35$

To find: center of the circle

Solution:

A circle is a locus of all points which are at equidistant from the fixed point (center).

Equation of a circle is of form $(x-a)^2+(y-b)^2=r^2$ where $(a,b)$ represents center of the circle and r denotes radius of the circle.

Given equation is $(x+12)^2+(y-9)^2=35$

$\left [ x-(-12) \right ]^2+(y-9)^2=35$

Compare this equation with $(x-a)^2+(y-b)^2=r^2$

Center is $(a,b)=(-12,9)$
