The Radius Of A Circle Is 12 Cm Select ALL Correct Statements class=

Sagot :

Answer:

B) 3.14(144)

D) 2(3.14)(12)

E) 3.14(24)

Step-by-step explanation:

The formula to find the area of a circle is [tex]\pi r^2[/tex], where r = radius, while the formula to find the circumference of a circle is [tex]2\pi r[/tex] or [tex]\pi d[/tex], where r = radius and d = diameter.

Given the information above, option B) is a correct statement because 12^2 equals 144, and once you're done solving the square, you multiply it by 3.14. Next, option D) and E) are correct, too, because they exactly follow [tex]2\pi r[/tex] and [tex]\pi d[/tex]. Furthermore, for E), diameter = twice the radius, so it makes sense to multiply 3.14 by 24.
