A biscuit recipe calls for the dough to be rolled out and circles to be cut from the dough. The biscuit cutter has a radius of 4cm. Find the area of the top of the biscuit once it is cut. Round to the nearest whole unit.

50.3 cm^2

Step-by-step explanation:

Given data

Radius= 4cm

The expression for the area of circle is

Area= πr^2

Area= 3.142*4^2

Area= 3.142*16

Area= 50.3 cm^2

Hence the area is 50.3 cm^2
