The radius of this ball is 15 inches. Which equation gives the ball's surface area, in square inches?
lilavasa [31]

Best to look up the formula for the surface area of a sphere and then find it:

A = 4πr^2, where r is the radius of the sphere.  Then,

A = 4π(15 in)^2 = 4(3.14)(225 in^2) =  2826 in^2 (answer)

This is represented by the formula given in the lower left.

For this figure what is the value of X?<br><br> How did you solve this?
Ivanshal [37]

Answer:

x=60

Step-by-step explanation:

This is a parallelogram.

For a parallelogram,

sum of angles in one side is 180.

we know, in a parallelogram,

the consecutive angles are supplementary or

their sum is  180.

So, we get,

x+33+87=180

or, x+120=180

subtracting   120

x+120-120=180-120

or, x=60

Rico thinks of a number between 30 and 40 that is represented by
Anna007 [38]
Hello,

x,y,z∈ IN

x=\frac{3}{4}*y
y=\frac{1}{3}*z

140
46\leq\ y\ \leq\ 50 ==>\ \frac{46*3}{4}\leq\frac{3y}{4}\leq\frac{50*3}{4}
35\ \leq\ z\ \leq\ 37==>
 x∈{35,36,37}
 y∈{47,48,49}
 z∈{141,144,147}

We must go futher:

if x=35 then y=4*35/3=46.666 not good , not whole
if x=36 then y=4*36/3=48 ok
if x=37 then y=37*4/3=49.333.. not good

So there is only one solution (36,48,144) for (x,y,z)

No problem with z for z=3/1*4/3*x=4x ==>whole.
