Answer: circumference = 2Πr²
Where r= 3
Π=3.14
Therefore Circumference = 2×3.14× 3²
= 2×28.26
Circumference=56.52
Formula:
Subtitute in 3 for r.
Solve and the answer is 28.26
Hello!
Distance between two points (2,9) and (6,3) -
<span>1. Take the Absolute Difference between the X points 2 and 6. The Absolute Difference is 4. </span>
<span>2. Square 4 = 16 </span>
<span>3. Take the Absolute Difference between the Y points 9 and 3. The absolute Difference is 12. </span>
<span>4. Square 12 = 144 </span>
<span>5 Add 144 + 16 = 160 </span>
<span>6. Take the Square root of 160 </span>
<span>12.6491106407
Hope this Helps at least! :)</span>
Answer:
A) Reflection.
Step-by-step explanation:
From the figure shown, we can see that the blue triangle is flipped about the x-axis to form the red triangle.
When an object is flipped about a line, then this transformation is called reflection about that line.
Thus, we can say that reflection is taking place in the figure shown in which the x-axis is acting like a mirror. The blue triangle is the pre-image and the red triangle is the image after reflection.
The reflection about x-axis is given by:
We can check the co-ordinates of the triangles and confirm the the transformation occurring
Points of pre-image triangle:
Points of image triangle
Thus, the transformation is reflection.
Answer:
~ 5(x-5)
Explanation:
~ Always find GCF to factorize a number, here it’s 5
~ Now inside the bracket the x stays the same but 25 divided by 5=5
~ Now we have 5(x-5)
We know that
[scale]=1 in / 30 in
scale=measure in the drawing/measure in the actual
[measure in the actual]=measure in the drawing/scale
the measure in the drawing are
3 in x 4 in
so
for 3 in
measure in the drawing=3 in
[measure in the actual]=3/(1/30)-----> 3*30------> 90 in
for 4 in
measure in the drawing=4 in
[measure in the actual]=4/(1/30)-----> 4*30------> 120 in
the measure in the actual are
90 in x 120 in
1 ft----------> is equal to 12 in
x-------------> 90 in
x=90/12-----> 7.5 ft
1 ft----------> is equal to 12 in
x-------------> 120 in
x=120/12-----> 10 ft
the measure of a bedroom in feet are
7.5 ft x 10 ft
the area=7.5*10--------> 75 ft²
the answer is
<span>the area of the room is 75 ft</span>²
