Answer:
You need to find the radius first,
Half of 23 is = 11.5
Formula you must remember when finding area of circle is:
πr^2
(pie (3.14 or 22/7) x radius squared)
Our pie is 3.14 because they said to use it in this particular question.
3.14 x 11.5^2 (remember we are making our radius squared) <--- Before
Let's evaluate first:
3.14 x 132.25 <--- After evaluating
So, 3.14 x 132.25 = 415.265 <----- your answer
_______
Answer: Because 4 is the base of what is being exponentially multiplied, you can multiply 256 by 4 to get 4^5
Answer:
y=6/5-5
Step-by-step explanation:
first find your <em>y-intercept</em> which is -5
then find your <em>slope</em> which is 6/5
and set your equation up as y=mx+b
which means <em>y equals slope times x plus your y-intercept.</em>
so your answer is
y=6/5x-5
