A circular object has a radius of 4 feet. Using the approximate π≈3.14 , estimate the circumference and area, rounded to the nearest 0.1. Area = sq. ft. Circumference = ft. please help very important

Step-by-step explanation:

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

Perimeter = 2πr

Where

r represents the radius of the circle.

π is a constant whose value is 3.14

Therefore,

Circumference = 2 × 3.14 × 4 =

25.1 feet rounded to the nearest 0.1

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

Area = πr²

Area = 3.14 × 4² = 50.2 square feet rounded to the nearest 0.1
