Answer:
C≈791.68
Step-by-step explanation:
C=2πr=2·π·126≈791.68135
27
This is because 18* of 23 is 4.14 which rounds to 4, and 23 + 4 = 27.
Area of the triangle = (1/2)*base*height
base = x
height = altitude = x+6
Area of the triangle = (1/2)*x*(x+6) = 108
(1/2)*x*(x+6) = 108
x²+6x-216 =0
(x+18)(x-12)=0
x=-18, or x=12
We can use only positive value, so x=12.
Base =12 cm.
