Answer:
12) s=
13) A=wh
14) p=a+b+c
15) A=
16) p-b-c=a
Step-by-step explanation:
12)
13) =W (multiply both sides by h)
14) take c to the other side of the equation( other side of the equal sign) it becomes a positive value
15) Divide both sides by 2
16) take b + c to the other side of the equation where it becomes -b-c
Answer:
radius = 5 in
Step-by-step explanation:
Using the formula for calculating the area (A) of a circle
A = πr² ( r is the radius )
here A = 78.5, hence
3.14r² = 78.5 ( divide both sides by 3.14 )
r² = = 25 ( take the square root of both sides )
r = = 5
