Answer:with?
Step-by-step explanation:
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.

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
Hello,
x,y,z∈ IN





==>
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.
