Answer:

Step-by-step explanation:

The diameter of a circle is twice its radius

d=2r

Substitute 7 in for r

d=2*7

d=14

So, the diameter is 14

Hope this helps! :)

tiny-mole [99]

Answer:

Step-by-step explanation:

(-4,8) & ( -4,2)

$Midpoint=\left(\dfrac{x_{1}+x_{2}}{2},\dfrac{y_{1}+y_{2}}{2} \right)\\\\\\=\left(\dfrac{-4-4}{2},\dfrac{8+2}{2}\right)\\\\\\=\left(\dfrac{-8}{2},\dfrac{10}{2} \right)$

= (-4,5)

How can I calculate a square root without guess and check?

Darina [25.2K]

By multiplying the same numbers.

2*2=4 *4 square root is 2

3*3=9 *9 square root is 3

4*4=16 *16 square root is 4

5*5=25 *25 square root is 5

Try this, maybe it will work :)

PQR has two known interior angles of 34°, and 80°. △RST has two known interior angles of 24°, and 90°. What can be determined ab

Shalnov [3]

Answer:

△PQR and △RST are not similar.

Step-by-step explanation:

In triangle △PQR, two known interior angles are 34° and 80°. So the measure of third angle is

$180-34-80=66$

In triangle △RST, two known interior angles are 24° and 90°.

$180-24-90=66$

Two triangles are similar if their corresponding angles are same and the corresponding sides are proportional.

Since the angles of △PQR and △RST are not same, therefore we can say that the △PQR and △RST are not similar.
