Answer:

530.66 cm²

Step-by-step explanation:

First, since the formula for the area of a ball is r² x 3.14, you multiply 13 by itself. Since 13x13 is 169, you do 3.14x169. Your answer should be 530.66 cm². (i don't know what the other one is, or if it's just a separate question.)

The graph of f(x) is obtained by translating the graph g(x)=|x| five units down.

lana [24]

F(x)=IxI-5
when you shift it up, add the units to the end of y=IxI
when you shift it down, subtract the units to the end of y=IxI

Find the area of the kite

Elanso [62]

For this case we have that the area of the kite is given by the area of two triangles, the triangles share the same base of 3 + 3 = 6 meters and one has height of 2m and the other height of 4m.

So, the total area is given by:

$A = \frac {1} {2} * 6 * 2 + \frac {1} {2} * 6 * 4\\A = \frac {1} {2} 12+ \frac {1} {2} *24\\A = 6 + 12\\A = 18$

Thus, the area of the kite is $18m ^ 2$

ANswer:

$18m ^ 2$
