A sphere has radius of 42 m. If the radius is divided by 6, what is the effect on the surface area? HELP ASAP!

1 answer:

7 0

A sphere with radius $r$ has surface area $4\pi r^2$ . Divide the radius by 6 and you get a surface area of $4\pi\left(\dfrac r6\right)^2=\dfrac4{36}\pi r^2$ , so that the final surface area is divided by 36.

The radius of the circle whose equation is (x-3)^2 + (y+1)^2 = 16 is

Firdavs [7]

Answer:

Step-by-step explanation:

The general equation of a circle with center (a, b) and radius r is given by the equation;

$(x-a)^{2}+(y-b)^{2}=r^{2}$

The constant in the right hand side of the equation is simply the square of the radius;

We have been given the following equation;

(x-3)^2 + (y+1)^2 = 16

Comparing this with the general equation above;

$r^{2}=16\\\\r=\sqrt{16}=4$
