How do I find the area of a circle with the diameter of 18 yards
(Is the value 3.14 for pie and do not round your answer)

81(pi) yards ^2

Step-by-step explanation:

Area=(pi)r^2

R=Radius

Radius=Diameter/2

r=9 yards

Area=(pi)*9^2

Area=81(pi) yards^2

254.34

Step-by-step explanation:

area of circle= (πd^2)÷4(d=diameter)

x=half

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!
