Answer:
8 cm
Step-by-step explanation:
The formula of circumference is c= πd------(1)
where C = circumference, π = 3.14 and d = diameter
as we know that diameter is equal to d= 2r
put the diameter formula in eq(1)
we get c= π2r-------(2)
from eq (2) separate r means radius
hence, r= c/(π2)------(3)
put the values in eq(3)
and radius is equal to 8 cm.
Answer:
180-88
92
Step-by-step explanation:
x=92
Answer:
Step-by-step explanation:
The interior angles of a triangle add up to 180 degrees, therefore:
40 + 40 + x-10 = 180
80 + x - 10 = 180
70 + x = 180
x = 110
< D = 110 - 10 = 100
