Question

A circular garden has a diameter of 2.4m. a) The garden is to be enclosed with plastic edging. How much edging is needed? b) The edging costs $4.53/m. You have a budget of $40.00. Will you have enough to buy the edging?

Answer 1

Answer:

Radius=

$\frac{diameter}{2}$

Answer of (A)

R=2.4/2

radius=1.2

length of plastic edging=circumference of circular garden=2πr

2×22/7×1.2

=7.536m=7.53m(apprx.)

Answer of (B)

cost=rate×area

cost=4.53×7.53=34.1109

which is less than $40.00

so $40 is enough to buy the edging
