Answer:

Surface area of a sphere=4πr

=154cm

⇒4×

=154cm

⇒r

154

⇒r

⇒r=

∴r=

=3.5cm

Volume of the sphere=

πr

×(3.5)

×42.875‬=179.67cm

EASY, answer this simple question :) *What kind of angles are 2 and 3?

IgorLugansk [536]

Answer:

∠2 = ∠3 is a pair of Vertical Angles.

Step-by-step explanation:

Whenever two lines intersect with each other, the angle formed between them is called Vertically Opposite Angle.

Here, line l intersects the traversal so,

the angle formed between them ∠1 and ∠4 are vertically opposite.

So, ∠1 = ∠4

Also, as ∠1 + ∠3 = ∠2 + ∠4 = 180° (LINEAR PAIRS)

So, ∠3 = ∠2 are also vertical angles.

Rewrite in simplest terms:

tangare [24]

Answer:

If one −5s−7(8s−1): -61s+7

If two −5s−7(8s−1): -112s+14

Step-by-step explanation:

-5s-7(8s-1)

Multiply -7 onto 8s and -1:

-5s-56s+7

add -5s and -56s:

-61s+7

−5s−7(8s−1)−5s−7(8s−1)

Multiply both -7 to 8s and -1

-5s-56s+7-5s-56s+7

add:

-112s+14
