Answer:
616 cm²
Step-by-step explanation:
To find the area of a circle you use the formula A = π · r²
So we know that the diameter is 28 cm, to find the radius we would divide this in half, because d = 2r, giving us 14. Now we can do 14² which is 196, and then times that by pi or in this case 22/7.
196 × (22/7) = 616
Rule of exponents:
when bases are the same - They are both x's - you add the exponents.
x^(-8 + -2) = x^(-10) or 1/x^10)
Answer:
The answer to your question is letter C.
Step-by-step explanation:
A. This option is wrong because that equation is of a horizontal parabola, an the graph shows a vertical parabola.
B. The same as letter A. This option is wrong because that equation is of a horizontal parabola, an the graph shows a vertical parabola.
C. This option is correct, is the equation of a vertical parabola and the negative indicates that it opens downward, as in the graph.
D. This option is incorrect because the equation is of a vertical parabola that opens upward.
Answer: yes.
