Answer:
4.32
Step-by-step explanation:
Percentage solution with steps:
Step 1: Our output value is 18.
Step 2: We represent the unknown value with X
Step 3: From step 1 above,$18=100%
Step 4: Similarly,x=24%
Step 5: This results in a pair of simple equations:
$18=100(1)
x=24(2)
Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both
equations have the same unit (%); we have
18/x=100%/24%
Step 7: Again, the reciprocal of both sides gives
x/18=24/100
Therefore the answer is 4.32

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.
