We know that
the axis is equal to the diameter of a sphere
so
D=14 units
r=D/2-----> r=7 units
<span>the surface area of the sphere=4*pi*r</span>²------> 4*pi*7²=196*pi units²

the answer is the option
<span>C. 196 pi units^2</span>

Answer:

The correct Option is C. 196 pi units²

Step-by-step explanation:

Length of the axis of sphere = 14 units

Also, the length of axis is twice the radius of the sphere

⇒ 2·radius = Length of axis

⇒ 2·r = 14

⇒ r = 7 units

Surface area of the sphere is given by the formula : 4π·r²

⇒ Surface Area = 4π × 7²

⇒ Surface Area = 4π × 49

⇒ Surface Area = 196π units²

Hence, The surface area of the sphere with the given dimensions = 196π units²

Therefore, The correct Option is C. 196 pi units²

A line had a slope of 2/3 and a y intercept at (0,14).What is the x intercept of the line?​
pychu [463]

Answer:

y=2/3x+14

Step-by-step explanation:

The standard form of an equation in slope-intercept form is y=mx+b where m=slope and b=y-intercept.

Given a y-intercept of 14 and a slope of 2/3, we can plug into the variables and get the equation y=2/3x+14

The x-intercept would be when y=0, so plugging in y=0 to the equation gets us:

0=2/3x+14

-14=2/3x

21=x

So the x-intercept is 21
