Answer:
A = 50.24 cm
Step-by-step explanation:
Area formula of a circle:
A = π r²
diameter- r+r
which means that your diameter(8) divided by 2 = 4
r of circle= 4
A= 3.14(4²)
A = 3.14(16)
A = 50.24 cm
Answer:
y > 13
Step-by-step explanation:
Inequality graph:
Your answer is the numerator
The denominator would be a power of 10. Then you could simplify
Answer:
(2^2)(z^7)
Explanation:
The quotient rule states that if two powers have the same base and are on opposite places of a fraction (one is on the numerator, the other on the denominator), you subtract the exponents.
First looking at the powers with the bases of 2, 2^8 is the numerator and 2^6 is the denominator. When we subtract 8-6 we get 2, so 2^8/2^6 would simplify to 2^2.
Then, we look at the powers with the base of z. z^10 is the numerator and z^3 is the denominator. When we subtract 10-3 we get 7, so z^10/z^3 would simplify to z^7.
