What is the area of half circle with a radius of 40 cm?

PLEASE HELPPP ILL GIVE BRAINLIEST

0.5027 square meters

Step-by-step explanation:

cm2

the 2 figures are congruent bc if you reflect abcd over the y axis then over the d axis the figures overlap

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!
