Answer:

<h3>Surface Area = 1,256 cm</h3>

<u>Solution:</u>

formula: Surface Area of a Sphere: 4π · r²

Surface area = 4π · r²

SA = 4(3.14) (10)²

SA = (12.56)(100)

SA = 1,256

On section AB, whose length is 192 cm, take the point C so that AC: CB = 1: 3. The point D is taken on the AC section so that CD

jasenka [17]

Answer:

112 cm

Step-by-step explanation:

<u>Given:</u>

AB = 192 cm
AC : CB = 1 : 3
CD = BC/12
The distance between midpoints of AD and CB = x

<u>Find the length of AC and CB:</u>

AC + CB = AB
AC + 3AC = 192
4AC = 192
AC = 192/4
AC = 48 cm

<u>Find CB:</u>

CB = 3AC = 3*48 = 144 cm

<u>Find the length of CD:</u>

CD = BC/12 = 144/12 = 12 cm

<u>Find the length of AD:</u>

AD = AC - CD = 48 - 12 = 36 cm

<u>Find the midpoint of AD:</u>

m(AD) = 36/2 = 18 cm

<u>Find the midpoint of CB:</u>

m(CB) = AC + 1/2CB = 48 + 144/2 = 48 + 82 = 130 cm

<u>Find the distance between the midpoints:</u>

x = 130 - 18 = 112 cm
