If angleb is 120 then AC is 120*2 = 240. 360-240 = 120 , 120/2 = 60 . If AB = 60 , angle adb is 30 and angle bdc is 30. DB is 2 * radius because angleA is 90. So with Pisagor AB = 3 , BC = 3 , AD = 3root3 and DC is 3root3.

Answer is = 6+6root3 = 6(1 + root3)

Surface area of hemisphere with diameter of 18

saul85 [17]

Answer:

In terms of pi: 243 $\pi$

in decimal form: 763.407

Step-by-step explanation:

to find surface area of a hemisphere the formula is,

$3\pi r^{2}$

diameter (d) = 18

radius = d / 2 = 18 / 2

radius = 9

$3\pi (9)^{2} \\3\pi (81)\\243\pi \\OR\\763.407$

What are the coordinates of point Q?

Lady bird [3.3K]

Answer:

Q (-4, -2); 2 units; Q' will be above the x-axis; 2 unites; no; yes, the y coordinates are multiplied by -1; Q' (-4, 2); R' (-2, 2), S' (1, 5), T' (-2, 5);

Step-by-step explanation:

even after a reflection over the x-axis, each points distance from the x-axis will stay the same

the x-coordinates don't change because the distance from the y-axis stays the same

the picture below shows points of Q'R'S'T', just connect the vertices

12.38 in expanded form

vitfil [10]

12.38 in expanded form is write like:-

10 + 2 + .3 + .08 = 12.38

To write a number in expanded form just means to write the number in a layout and when you add it up it will become the number you needed to write in expanded form.

So, 12.38 written in expanded form is:- 10 + 2 + .3 + 0.8

Hope i helped ya!!
