Answer:
c. 122.1 cm
Step-by-step explanation:
so l * w + 
since 6 cm is the diameter
6/2 = 3
the radius (or r) is 3
so 18 * 6 + 
108 + 
108 + 
108 + 14.13 = 122.13
simplified: 122.1 cm
hope this helps:)

Step-by-step explanation:
Answer:
a) 7/4 b) 5 c) 2
Step-by-step explanation:
Logrithmic Rule for a and b
Let a, M, N be positive real numbers.
a)
logaM - logaN = loga(M/N)
log9(7) - log9(4) = log9 (7/4)
b)
logaM + logaN = logaMN
log2 (x) + log2(9) = log2(45)
x9=45
(x9)/9 = 45/9
x = 5
c)
Change of base formula.
logb(x)=logd(b)/logd(x)
x log6(5) = log6(25) divide each term by log6(5)
x log6(5) / log6(5) = log6(25) / log6(5) Cancel common factor log6(5)
x = log6(25) / log6(5)
x = log6(5^2) / log6(5)
Expand log6(5^2) by moving 2 outside the logarithm.
x = 2log6(5) / log6(5) cancel the like term log6(5)
x = 2
Answer: multiply 8 on all x number of books read
Step-by-step explanation:
1 is 8 because 8 × 1 is 8
2 is 16 because 8 × 2 is 16
3 is 24 because 8 × 3 is 24
4 is 32 because 8 × 4 is 32
5 is 40 because 8 × 5 is 40
6 is 48 because 8 × 6 is 48
7 is 56 because 8 × 7 is 56
8 is 64 because 8 × 8 is 64
9 is 72 because 8 × 9 is 72
10 is 80 because 8 × 10 is 80
