Answer: 153.86cm
Step-by-step explanation:
A bowl represents a circle
Area of a circle is pir2
But here we are given the diameter as 14
Diameter = 2radii
14=2r
R=14/2
R=7
So radius of the bowl is 7cm
Back to the formula
Area of a circle is pir2
Pi=3.14
Substitute for each value
Area= 3.14×7^2
Area= 3.14×49
Area= 153.86cm
Area= ~154cm
Step-by-step explanation:
