Hello There!
Surface area of a sphere formula:
4πr²
SA = 4π14.21²
SA = 2537.5mm³
Surface area of a cone formula:
1/3πr²5
SA = 1/3π3²15.1
SA = 142.3in³
Pyramid:
SA = 124.3
Hope This Helps You!
Good Luck :)

Answer:
gcf is 
Step-by-step explanation:
we are given
and 
Firstly, we will find factors of both expression


now, we will find common factors among them
we can see that
For finding gcf, we always find common factors
so,
common terms are 3,m^2 and n
so, gcf is


25,678 rounded to the nearest 10,000 would be 30,000
Answer: (a) e ^ -3x (b)e^-3x
Step-by-step explanation:
I suggest the equation is:
d/dx[integral (e^-3t) dt
First we integrate e^-3tdt
Integral(e ^ -3t dt) as shown in attachment and then we differentiate the result as shown in the attachment.
(b) to differentiate the integral let x = t, and substitute into the expression.
Therefore dx = dt
Hence, d/dx[integral (e ^-3x dx)] = e^-3x
You have to divide 86 by 18 .which she can make about 5 necklaces
