Find the area of a circle with diameter 5mm. Use the value 3.14 for pi, and do not round your answer. Be sure to include the correct unit in your answer.

19.6375 mm^2

Step-by-step explanation:

Given data

Diameter = 5mm

Radius= 5/2= 2.5mm

The expression for the area

A=πr^2

Substitute

A=3.142*2.5^2

A=3.142*6.25

A=19.6375 mm^2

16.9 times 2.85

step-by-step explanation:

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!
