Answer:17
Step-by-step explanation:
First you subtract 13-9 to find the distance between the 2 numbers. That gets you 4 but if the numbers are 2 spaces away from one another then that means that the number line increases by 2. Then you add 4 to 13 and that’s how you get 17.
Answer: 137π
The usual formula for a circle centered at (a,b), with radius r,
(x - a)² + (y - b)² = r²
The area of the circle is πr², so 137π
Hey user!
your answer is here..
we know about EULER'S FORMULA, it is a formula used to verify a polyhedron or to calculate the number of faces, vertices or edges.
Euler's formula = F + V - E = 2
given :-
faces = 28, verticies = 50 and edge = ?
we know that F + V - E = 2
therefore 28 + 40 - E = 2
==> 68 - E = 2
==> - E = 2 - 68
==> - E = - 66
==> E = 66
hence, the number of edges of the polyhedron is 66.
cheers!!
Answer:
D. 59.66
Step-by-step explanation:
The formula is <em>A = ![\pi r^{2}[/tex\ Also the radius is half of the diameter. and [tex]\pi](https://tex.z-dn.net/?f=%5Cpi%20r%5E%7B2%7D%5B%2Ftex%5C%20%3C%2Fem%3EAlso%20the%20radius%20is%20half%20of%20the%20diameter.%20and%20%5Btex%5D%5Cpi)
= 3.14</em>
so we need to find the area's
9 x 9 = 81
81 x 3.14 = 254.34
Next circle.
10 x 10 = 100
100 x 3.14 = 314
Now to find the difference.
314 - 254.34 = 59.66
59.66
