Answer:
9.684925e-7
Step-by-step explanation:
Okey so the area of a circle is taken from the equation πr²
now in the sum they have given information as: area of one small circle is 9π
that means :
area of small circle = πr²
= π3²
= π9
so in the sum they have given us the radius of one circle as 3
from this information we understand that the diameter of one small circle should be = 3 ×2
= 6 (as diameter is twice the radius)
we are given 3 of these circles. that means there are 3 times the diameter measured.
so the diameter of the large circle is = 6×3 = 18
as we calculated, since 18 is the diameter of the large circle, it should be taken ½ for radius.
radius of large circle = 18÷2
= 9
now we know the radius of large circle.
taking the equation 'πr²' to find the area:
area of large circle = πr²
= π9²
= π81
your answer is 81π
I got 0.416667, but.......im not sure thats right...
Answer:
x=60 degrees
Step-by-step explanation:
Since all of the sides are the same (we know that because of the dash marks on the sides) you take the number that all the angles of triangles added up equals which is 180 and divide by 3 which is 60
