2. The area for a circle is as follows:
A = π

The radius of the circle is 4 in, so we plug that into the equation.
A = π (4

)
4

= (4 in.)(4 in.) = 16

A = 16π

This is the area for the whole pizza, so divide that by 2 to get the area of the pepperoni
a) 8π

For the bacon, we can just divide the value we already have by 2, since it is half the area of the pepperoni
b) 4π

3. This question is asking for the circumference, whose equation is as follows:
C = 2 π r
We can use the area formula, A = π

to find the radius of this circle
36π = π

Divide both sides by π:
36 =

Square root both sides:
r = 6 in.
Plug in this value to the circumference formula, C = 2 π r
C = (2)(π)(6 in.)
Your final answer is:
C = 12π in.
Answer: b= - -log10(7)+3/2
Step-by-step explanation: log 10 (7) -2b-9=-6 : b= - -log10(7)+3/2 (Decimal : b = -1.07745...)
so these are the steps how I got it I did log 10 (7)-2b-9=-6 subtract log 10 (7) -9 from both sides log 10 (7)-2b-9-(log10(7)-9)=-6-(log 10 (7) -9)
Simplify -2b= -log10(7)+3
Divide both sides by -2 -2b/2= - log 10(7)/-2+ 3/-2 if you simplify it should give you b= - -log10(7)+3/2 that should be your answer but i'm not sure those I think that's how you do it let me know if you got it right bye!
Answer:
x=25
Step-by-step explanation:
all you do to find x is subtract 30 from 5 and you get 25 you double check by replacing x for 25 and there is your answer!
