Please help me with this problem

The perimeter is 96 ft

Step-by-step explanation:

Step 1:  Add the given sides

9 + 9 + 9 + 9 + 9 + 9 + 30 + (30 - 9 - 9)

84 + (12)

96

(30 - 9 - 9) gives us the opposite side of 30 ft

 The perimeter is 96 ft

it could be 1,3 and more others to create a cylinder.

step-by-step explanation:

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!
