Textbook Problem

Sue and Dave’s semicircular driveway is to be resealed, and then flowers are to be planted on either side.(Give approximate answers.)a) What is the number of square feet to be resealed?b) If Dave can reseal the driveway at a cost of \$0.45 per square feet, what is the cost of resealing the driveway?c) If individual flowers are to be planted 1 foot from the edge of the driveway at intervals of approximately 1 foot on both sides of the driveway, how many flowers are needed? To determine

(a)

To find:

The number of square feet to be resealed.

Explanation

Formula:

The area of the semi-circle A=12πr2.

Calculation:

Consider the following diagram:

We need to find the number of square feet to be resealed.

We determine the area of ring:

OB=ODBD=ODAC=3012=18

Aring=Abig semi-circleAsmall semi-circle=π(OD2)2π<

To determine

(b)

To find:

The cost of resealing the driveway.

To determine

(c)

To find:

The number of flowers are needed to be planted 1 foot from the edge of the driveway.
