Consider the equation 0.75⋅10^w/3=30

Mathematics
1 answer:
Nastasia [14]3 years ago
5 0

Answer:

The value of w is:

w=3\cdot log_{10}(40)

Step-by-step explanation:

We have to calculate w from the equation

0.75\cdot 10^{w/3}=30

The solution has to be expressed as a logarithm in base 10.

We can solve it like:

0.75\cdot10^{w/3}=30\\\\10^{w/3}=30/0.75=40\\\\(w/3)log_{10}(10)=log_{10}(40)\\\\w/3=log_{10}(40)\\\\w=3\cdot log_{10}(40)

The value of w is:

w=3\cdot log_{10}(40)

Plug in 3.14 for pi and 4 for the radius.

C = 2(3.14)(4)

Multiply.

C = 25.12
