kolezko [41]

Answer: Area of circular plate is 36.5 square inches

Step-by-step explanation:

The formula for determining the circumference of a circle is expressed as

Circumference = 2πr

Where

r represents the radius of the circle.

π is a constant whose value is 3.14

From the information given,

Circumference of circular plate = 21.4 inches. Therefore

2 × 3.14 × r = 21.4

6.28r = 21.4

r = 21.4/6.28

r = 3.41 inches

The formula for determining the area of a circle is expressed as

Area = πr²

Area of circular plate = 3.14 × 3.41² = 36.5 square inches

A farmer wants to build a rectangular garden 10ft long and 6ft wide. How many feet of fencing should he buy?
Lana71 [14]
He should buy 32 feet of fencing. I got 32 by just finding the perimeter or in other words adding 10+10+6+6 which equal 32. You would NOT do area or 10×6 because that would include that land within the fenced area and who wants 60 feet of fencing that you can't put anything in?

Good luck, hope that helped.
