Answer:
The answer is 314cm²
the formula for the sphere area of a sphere is:
A= 4TT²
A = 4x3.14x5²
first solve for exponents
A = 4x 3.14x25
then multiply
A = 314cm²
Answer:
Explanation:
The problem we are given is
We can write the square root of a fraction as a fraction with a separate radical for the numerator and denominator; this gives us
We can write the whole number 4 as the fraction 4/1; this gives us
We now need to "rationalize the denominator." This means we need to cancel the square root in the denominator. In order to do this, we multiply both numerator and denominator by √(2x); this is because squaring a square root will cancel it:
When multiplying radicals, we can extend the radical over both factors:
Answer: i really dont know
Step-by-step explanation:
First can you change
2x + y = -12
To have y as the subject
Looks like y = ???
