$(-4)(-9)\\\mathrm{Remove\:parentheses}:\quad \left(-a\right)=-a,\:-\left(-a\right)=a\\=4\times\:9\\= 36$

$(-4)(9)\\\\\mathrm{Remove\:parentheses}:\quad \left(a\right)=a\\=-4\times\:9\\\\\mathrm{Multiply\:the\:numbers:}\:4\times\:9=36\\=-36$

$(6)(6)\\\\\mathrm{Remove\:parentheses}:\quad \left(a\right)=a\\=6\times\:6\\\\\mathrm{Multiply\:the\:numbers:}\:6\times\:6\\=36$

$(-6)(-6)\\\\\mathrm{Remove\:parentheses}:\quad \left(-a\right)=-a,\:-\left(-a\right)=a\\=6\times 6\\\\\mathrm{Multiply\:the\:numbers:}\:6\times\:6\\=36$

$(6)(-6)\\\\\mathrm{Remove\:parentheses}:\quad \left(a\right)=a\\=-6\times 6\\\\\mathrm{Multiply\:the\:numbers:}\:6\times \:6=36\\=-36$

Find the area of this circle use 3.14 or 22/7 or pie round your answer to the nearest hundred if necessary

notka56 [123]

Answer:

The area of the circle is 50.24 mm ²

Step-by-step explanation:

To solve this exercise we need to use the area formula of a circle:

a = area

r = radius = 4mm

π = pi = 3.14

a = π * r²

a = 3.14 * (4mm )²

a = 3.14 * 16mm ²

a = 50.24 mm ²

The area of the circle is 50.24 mm ²
