(i.) The height of the entire object is 10 cm. The radius of the hemisphere is 4 cm, which is also the height of the hemisphere. So, you would subtract 10 by 4 and get 6 cm as the height of the cone.

(ii.) Cone:
v = ​(1/3)πr​^2​​h
v = (1/3)π(4^2​​)*6
v = (1/3)π(16*6)
v = (1/3)π*96
v = 32π
v = 100.5 cm^3

Hemisphere:
v = ​(2/3)πr​^3
v = (2/3)π(4^3)
v = (2/3)π*64
v = 42.7π
v = 134.1 cm^3

Added together:
100.5 + 134.1 = 234.6 cm^3

=785.63-182
=603.63

Write this number in standard form. 300+80+0.9+0.06+0.001
Lina20 [59]

Hey there! I'm happy to help!

First, let's add the hundreds and the tens.

300+80=380

We see that there is nothing in the ones place, so we keep our ones place 0 and we move onto adding the tenths.

380+0.9=380.9

We add the hundredths.

380.9+0.06=380.96

And finally, we add the thousandths.

380.96+0.001=380.961

Therefore, this number in standard form is 380.961.

Have a wonderful day! :D

If pqr = 1 , rst = 0 , and spr = 0, which of the following must be zero?
ahrayia [7]
P,Q,R can't be 0, because their product is nonzero. Either of S and T could be 0, but the third one only works if S is 0.

Factor completely 2x3 + 8x2 + 3x + 12.
goblinko [34]

Answer:

(2x^2+3)(x+4).

Step-by-step explanation:

2x^3+8x^2+3x+12

We need to find the factors of given equation;

Solution:

On Solving the above equation we get;

Now First we will take common factor from first 2 terms which is 2x^2 we get;

2x^2(x+4) + 3x+12

Now we will take the common factor from the last 2 terms which is 3 we get;

2x^2(x+4) + 3(x+4)

Here we get 2 terms in which (x+4) is common factor.

(x+4)(2x^2+3)

Hence After factorizing the given equation we get (2x^2+3)(x+4).
