Deffense [45]3 years ago

Answer:

B

Step-by-step explanation:

a³ + b³ = (a + b)(a² -ab + b²)

27 = 3* 3 * 3 = 3³

64 = 4 * 4 * 4 = 4³

27a³ + 64b³ = 3³a³ + 4³b³

                    = (3a)³ + (4b)³        

                    = (3a + 4b) ( [3a]² - 3a*4b + [4b]²)

                    = (3a + 4b) (9a² - 12ab + 16b²)

If the circumference is 16pi then what is the area
salantis [7]

Answer:

A = 64 pi

Step-by-step explanation:

The circumference can be found by

C = 2 * pi *r

16 pi = 2 * pi *r

Divide each side by 2 pi

16 pi/ 2 pi = 2 * pi *r/ 2 pi

8 =r

The radius is 8

To find the area

A = pi r^2

A - pi (8)^2

A = 64 pi
