Help me pls thanks so much

A) 5 in

B) 3.93 in

C) 11.8 in

Step-by-step explanation:

A) 10π/π = 10in diameter

10/2 = 5 in radius

B) 10π/8 = 3.93 in

C) 3.93 x 3 = 11.8 in

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!
