A circle circumference is approximately 76 cm estimate the radius diameter and area of the circle

r = 12.1cm, d = 24.2cm, Area = 460.0cm²

Step-by-step explanation:

From the formula,

Circumference of a circle = πd or 2πr.

To find the radius, we have to equate 76 cm to πd or 2πr and make r or d the subject of the formula. Now

76 = 2πr, don't forget that

π = 22/7 or 3.142

Now make r the subject of the formula

r = 76/2π

= 76/2 x 3.142

= 76/6.284

= 12.1 cm

d = 2r

= 2 x 12.1

= 24.2cm.

Area of the circle is πr²

= 3.142 x (12.1)²

= 3.142 x 146.41

= 460.0 cm²
