Answer:
A = 27π
P =
Step-by-step explanation:
Well if it follows the same proportions as a square then the dotted line is 6 cm.
<u> Triangle </u>
So the area of a triangle is b*h / 2
b = 6
h = 6
6*6 = 36
36 / 2 = 18
A = 18cm^2
So to find the missing side or c we do 6^2 + 6^2 = c^2,
36 + 36 = c^2
72 = c^2
≅<u>8</u>
6 + 6 + 8
= 20cm
<u> Half circle </u>
Now the area of a semicircle is,
pi r^2 / 2
So if the diameter is 6 then the radius is 3.
So we do 3*3 = 9
9 * pi = 9π^2
Perimeter: 6π

Answer:
22
Step-by-step explanation:
198 = 2×3²×11
For 198n to be a perfect square, each prime factor must have an even exponent. So the smallest 198n would be:
198n = 2²×3²×11²
198n = 4356
n = 22
Answer:
D.
Step-by-step explanation:
This will be D because the beaker already has 0.2 mL of water. If Jovita needs to add more water to the beaker, and<em> then </em>it is 0.8. In D, the diagram shows you 0.2 + x = 0.8, which makes it the right diagram.
Hope that helps!
Answer:
y = 8
Step-by-step explanation:
if you do -2 + -2 and add ten to it you get 8
