Find the area of this semi-circle with radius, r
= 4cm.
Give your answer as an expression in terms of
π

8π

Step-by-step explanation:

General formula for area of a circle:

the question asks for half of a coracle, namely, a semicircle. thus, we multiply the area of a full circle by half

= 8π

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!
