Find the circumference and area of the circle​
ser-zykov [4K]

Answer: C = 53.3 inches

A = 226.1 inches²

Step-by-step explanation:

The inscribed square has equal sides. To determine the hypotenuse of the square which is also the diameter of the circle, we would apply the Pythagoras theorem which is expressed as

Hypotenuse² = opposite side² + adjacent side²

Hypotenuse² = 12² + 12² = 144 + 144 = 288

Hypotenuse = √288 = 16.97 inches

Radius = diameter/2 = 16.97/2 = 8.485 inches

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

Circumference = 2πr

Circumference = 2 × 3.14 × 8.485 = 53.3 inches

Area = πr²

Area = 3.14 × 8.485² = 226.1 inches²

Help me !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
ElenaW [278]
So 20% is 1/5 as a percent.

So 1/5 multiplied by 5 equals 5/5, or 1.

So if 1/5 = 6, then 6 multiplied by 5, or 30, must equal 5/5, or 1.

So the total number of dolls in Amyia's doll collection is 30.
