Either the radius or diameter of a circle is given below. Find the area of the circle based on the information given. First, express the area in terms of pi. Then, round your answer to the
nearest tenth of a unit.
(a) r =4 in
(b) r = 24 in
(c) r = 9 m
(d) d = 22 yd
(e) d = 16 cm
(f) d=1 ft

answer: x=3 and y=4

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!
