The area of any circle is (pi) · (radius)² .
The radius is 1/2 of the diameter.
For your circle, the radius is 1/2 of 14 inches = 7 inches,
and the area is
(pi) · (7 inches)²
= (pi) · (49 square inches)
= 153.9 square inches (rounded)
Answer:
y=3/4x+-3
Step-by-step explanation:
first use rise over run to find the slope. go up 3 and over four making the slope 3/4. nxet locate the y-intercept which is clearly at -3. now just substitute the values into the equation y=mx+b
Answer:
Step-by-step explanation:
The equation is x<= 5.
So 5 and all the numbers less than 5 would be an answer for x.
So you would put a closed dot on 5, because x can equal 5. Then put a line pointing right to all the numbers less than 5.
Are you sure you want ONLY the coefficient of b? If you expand this, you will have b in 3 of 4 terms.
According to Pascal's Triangle, the coefficients of (a+b)^4 are as follows:
1
1 2 1
1 3 3 1
1 4 6 4 1
So (a+b)^4 would be 1a^4 + 4a^3b + 6a^2b^2 + 4ab^3 + b^4
Here, you want (3 + b)^4. Here's what that looks like:
3^4 + 4[3^3*b] + 6[3^2*b^2] + 4[3*b^3] + 1[b^4]
Which coeff did you want?
Answer:
x > 8

I hope this helps you out!
