2x+6=x-3
if you also need the answer it's x=-9
Answer:
Step-by-step explanation:
The cross-section of a sphere is a circle . The area of a circle can be calculated by the formula A= Where r is the radius of the circle.
Given :
Solving for r we have:
Or r= 10.
The area of a sphere is calculated by the formula :
Substituting r value we have:
SA=
The total surface area of this sphere is 400π .
Y=t+12 this is one the answers
