Find the perimeter and the area of a circle when radius is 10 cm.
Note:
✯ No spam
✯ No short answers
Answer:
Step-by-step explanation:
Using 3.14 as pi.
Perimeter of a circle = 2*pi*radius
= 2*3.14*10
= 62.8 cm
Area of a circle = pi*radius*radius
= 3.14*10*10
= 314 cm^2
Solution:
Formulas to remember:
Circumference of circle = 2πr (r = radius)Area of circle = πr² (r = radius)Finding the circumference of the circle:
Circumference of circle = 2πr=> Circumference of circle = 2 x 22/7 x 10=> Circumference of circle = 44/7 x 10=> Circumference of circle = 440/7 ≈ 62.86 cmFinding the area of the circle:
πr² = Area of circle=> 22/7 x 10 x 10 = Area of circle=> 22/7 x 100 = Area of circle=> Area of circle = 2200/7 cm² ≈ 314.29 cm²PLEASE HELP ! SURFACE AREA

Step-by-step explanation:
Add the areas of all of the polygons in the area net which represent the sides of the triangular prism:
SA = 2 small rectangles + 1 big rectangle + 2 small triangles
SA = 2(3 * 7) + (6 * 7) + (6 * 2)
= 42 + 42 + 12
= 84 + 12

Can someone help me with this
Answer:
Bottom box= 103/210
Middle-right box=19/30
Middle-left box=7/21
Step-by-step explanation:
we can convert 1/7 to 21ths so it will be easier to add.
1/7 = 3/21
so, 3/21 + 4/21 = 7/21
we can now use that to find the box next to it.
The LCM (lowest common multiple) of 21 and 30 is 210.
7/21 = 70/210
29/30 = 203/210
so 203/210-70/210 = 19/30 (simplified)
and finally, we can use this to work out the fraction in the bottom box.
LCM of 30 and 7 is also 210.
so 1/7 = 30/210
19/30 = 133/210
so 133/210 - 30/210 = 103/210.

do these have the same horizontal asymptote or no?
which is the answer and why? Pls i’ll give good points. :)
Answer:
y=(x+2)(x-5)
Step-by-step explanation:
The roots of the function (where it touches the x axis) are (0,-2) and (0,5), so you have to pick the equation with those roots. This equation if y=(x+2)(x-5). This is because when y = 0, when you insert those roots as x values the right side also equals zero. For example:
0=(x+2)(x-5)
set x as -2
0=(-2+2)(-2-5)
0=0*-7
0=0
The same would also happen if you inserted 5, showing that this equation is the correct one for this set of roots.

To find the area of a rectangle, multiply its height by its width. For a square you only need to find the length of one of the sides (as each side is the same length) and then multiply this by itself to find the area.
What is the value of x if the angles are supplementary?
1.) 60
2.) 50
3.) 40
4.) 30
Answer:
2) 50
Step-by-step explanation:
Basically, supplementary is when you add two angles, they should equal 180 degrees. In this picture, we can see that the bottom two rays form a straight line, indicating that it is a 180-degree angle, also. Great way to visualize, by the way. Well, 180 - 130 is 50 degrees, so x is equal to 50 degrees.
Answer:
2) 50
Step-by-step explanation:
x + 130 = 180
-130 -130
x = 50
