Answer:
Your answer would be B: 30 ft squared
Step-by-step explanation:
Find the area of the circle: 5.5 (radius) multiply it by itself then multiply that by 3.14 which gets you 94.985. Now find the area of the square which is 8*8 = 64. Subtract 64 from 94.985 and your answer will be 30.985. The questions asks for the approximate (estimate), so the closest one would be 30 ft squared
Answer:
Step-by-step explanation:
<u>1) Find the radius</u>
We can do this by using the distance equation with the centre (7,1) and the given point (-1,-5):
where the two points are 
and 
Plug in the points (7,1) and (-1,-5)
Therefore, the radius of the circle is 10 units.
<u>2) Plug the data into the equation of a circle</u>
Equation of a circle (when not centred at the origin):
where the centre is 
and r is the radius
Plug in the centre (7,1) as (h,k)
Plug in the radius 10

Answer:
hello its (1/4)x+4=3
Step-by-step explanation:
Answer:
Para poder definir los radianes, es necesario introducir el concepto de ángulo central. Un ángulo central es un ángulo cuyo vértice está en el centro de un círculo. En el círculo siguiente, el centro es el punto O, la longitud del radio es r, y es el ángulo central y 30 grados equivale a vil.
