The shortest side of a polygon of area 196 sq. in. is 4 in. long. Find the area of a similar polygon whose shortest side is 8 in

fenix001 [56]

The correct answer is: " 784 in² " .
_________________________________________
                  {or; write as: " 784 sq. inches " .}.
_________________________________________
      When the side is doubled (in this case, 4 is doubled; 4 * 2 = 8} ; the area is increased by 2² times; that is, by 4 times; so, the area is:
    (196 sq. in) * 4 =   784 sq inches .

Solve:

harina [27]

Answer:

$x = 0$

Step-by-step explanation:

Write the number in exponential form with the base of 2:

${2}^{x - 3} = {2}^{ - 3}$

Since the bases are the same, set the exponents equals.

$x - 3 = - 3$

Cancel equal terms on both sides of the equation:

$x = 0$

13. The radius of Earth is approximately 6.4 x 100 m. Use the formula V = 4/3pr^3

romanna [79]

<u>We are given</u>

Radius of Earth; 6.4 x 100 meters = 640 meters

Clearly, the shape of the earth is a sphere. Thus, to determine the volume of the earth, we will use a formula that determines the volume of a sphere.

$\implies \text{Volume of sphere =} \ \dfrac{4\pi r^{3}}{3}$
