Answer

(1/10) of Area = 3.85 cm²

Step-by-step explanation

Circumference of a circle = 2πr

where

π = pi = (22/7)

r = radius of the circle = ?

Circumference = 22 cm

Circumference = 2πr

22 = 2 × (22/7) × r

22 = (44r/7)

(44r/7) = 22

44r = (22)(7)

r = [(22)(7)/44]

r = 3.5 cm

Area of a circle = πr²

We are then asked to find (1/10) of the area of this circle

(1/10) of Area = (1/10) × (22/7) × 3.5²

(1/10) of Area = 3.85 cm²

Hope this Helps!!!
