Answer:
The area of the circle is 153.86 u²
And the expression is
a = π * (7 u)²
Step-by-step explanation:
To solve this problem we need to use the area formula of a circle:
a = area
r = radius = 7 units
π = 3.14
a = π * r²
we replace with the known values
a = π * (7 u)²
a = 3.14 * 49 u²
a = 153.86 u²
The area of the circle is 153.86 u²
