Semi circle - 31.81 (rounded)
Step-by-step explanation:
find the area of the triangle which is 1/2 6*5.2 -=15.6
there are 6 triangles so that means it has to be multiplied by 6 - 15.6*6 = 93.6
Use the semi cirlce formula- (pi*r^2)/2
In this situation that is (pi*4.5^2 )/2 = 31.81 (rounded)
Answer:
n = -4
Step-by-step explanation:
6n + 9 = -3n - 21 - 6
combine like tmers:
6n + 9 = -3n - 27
add 3n to both sides:
9n + 9 = -27
subtract 9 from both sides:
9n = -36
divide by 9:
n = -4
