Answer:

option b. $EF:AD=2:1$

Step-by-step explanation:

we know that

In a circle the ratio of the diameter to the radius is equal to $2:1$

because

$D=2r$

$2r/r=2:1$

In this problem

EF is a diameter

AD is a radius

therefore

$EF:AD=2:1$

Answer:

total sales price = $21,000

Step-by-step explanation:

given data

depth = 80 feet

sold = $350 per front foot

to find out

total sales price

solution

front feet = 60

so total sales price will be

total sales price = 60 × $350 per front foot

total sales price = $21,000
