Answer:
false
Step-by-step explanation:
the formula for the area of a circle is πr^2
π=3.14
r= 1/2 of diameter = 6
3.14 x 6^2
=113.04cm2
The answer to this question is B
First, you need to find the mean of all this set of numbers. You would add them all together and then divide by 6 which is 50.5.
Now you find the sample variance. Subtract each number from the mean.
<span>15.5, 13.5, 8.5, -6.5, -10.5, -19.5 </span>
After, you square each value and add them.
<span>240.25+182.25+72.25+42.25+110.25+380.2... </span>
<span>= 1027.5 </span>
Now divide by 5 (because it's a sample variance) and you get 205.5.
Answer: 84 cm^2
Step-by-step explanation:
1/2bh
1/2(6x4)
1/2(24)
12
*multiply that by 4 for all of the sides*

(6x6)
36
add them together to get 84 :) <3
Answer:
<em>Option B</em>
Step-by-step explanation:
We can approach this problem through the formula for distance between points, but I can think of a more easier approach. This line forms a triangle with the x and y axis, a right triangle with the legs being 2 and 1 units. The line with which we must find the distance of acts as the hypotenuse of this triangle, so let us apply Pythagorean Theorem to solve for the length of the line;
