A shape is similar if corresponding angles are equal & if one is an enlargement of the other.

(I. E., one shape is twice as big as the other one.)

So, compare the lengths to find a common scale factor (of 2, for example, where you multiple by 2 to get a value & divide to get original value, from one shape to another.)

Hope this helps!

What can be added to -1 so it can be a positive 1?
Tanzania [10]
So represent missing number with x
x means unknown so
x+-1=+1
adding a negative means subtraction
x-1=1
you can do anything to an equation as long as you do it to both sides
add 1 to both sides
x+1-1=1+1
x+0=2
x=2

the number is 2

Find the distance between these points.<br>A (5.8). B(-3.4)<br>AB =​
Law Incorporation [45]

Answer:

AB=8.94427191 (leave a comment if you need it rounded)

Step-by-step explanation:

First, plug these into the distance formula. (d= √(x2-x1)^2+(y2-y1)^2)

d=√(-3-5)^2+(4-8)^2

Now, solve the problem.

d=√(8)^2+(-4)^2

d=√64+16

d=√80

d=8.94427191

Find the surface area of the cone shown. Find the surface area of a cone with the same slant height and triple the diameter. Use
KonstantinChe [14]

Answer:

surface area = 8704.08 cm²

Step-by-step explanation:

The surface area of a cone is given by the formula;

SA = πr² + πrL

Where r is radius and L is slant height

We are given;

Diameter = 24cm

Slant height; L = 41 cm

We are told that this new cone has a diameter that is triple of the one given.

Thus, new diameter = 24 x 3 = 72 cm

Thus, Radius; r = 72/2 = 36 cm

SA = π(36)² + π(36)(41)

SA = (3.14 * 1296) + (3.14 * 1476)

SA = 8704.08 cm²
