if 1000 spherical of radius 1 cm are melted to form a bigger bulb. Then find the radius of bigger bulb

never [62]

Answer:

10 cm

Step-by-step explanation:

Given:

No. of small spherical bulb = 1,000

radius (r) of smaller bulbs = 1 cm

Required:

radius of the bigger bulb

SOLUTION:

The following equation represents the relationship of the volume of the smaller and bigger bulb,

$\frac{V_2}{V_1} = 1,000$

Where,

$V_2$ = volume of bigger bulb

$V_1$ = volume of smaller bulb

1,000 is the number of smaller bulbs melted to form the bigger bulb.

Volume of a sphere is given as, ⁴/3πr³

Therefore:

$V_2$ = ⁴/3*π*r³ = 4πr³/3

$V_1$ = ⁴/3*πr³ = ⁴/3*π*(1)³ = ⁴/3π*1 = 4π/3

Plug the above values into the equation below:

$\frac{V_2}{V_1} = 1,000$

$\frac{\frac{4*pie*r^3}{3}}{\frac{4*pie}{3}} = 1,000$

$\frac{4*pie*r^3}{3}*{\frac{3}{4*pie} = 1,000$

$\frac{4*pie*r^3*3}{3*4*pie} = 1,000$

$\frac{12*pie*r^3}{12*pie} = 1,000$

$r^3 = 1,000$ (12pie cancels 12 pie)

$r = 10$ (taking the cube root of each side)

Radius of the bigger bulb = 10 cm

3.2.PS-33 Liam has 63 CDs, Alex has 49 CDs, and Michael has 77 CDs. Use the GCF and the Distributive Property to find the tota

labwork [276]

Answer:

The total number of CDs Liam, Alex, and Michael have is <u>189</u>.

Step-by-step explanation:

Given:

Liam has 63 CDs, Alex has 49 CDs, and Michael has 77 CDs.

Now, to find the total number of CDs using the GCF and the Distributive Property.

So, the CDs are :

Liam = 63.

Alex = 49.

Michael = 77.

Now, we factorize all the Number of CDs of Liam, Alex and Michael to get the GCF:

The factors of 63 are: 1, 3, 7, 9, 21, 63

The factors of 49 are: 1, 7, 49

The factors of 77 are: 1, 7, 11, 77

Thus, 7 is the GCF.

Now, we use the distributive property to get the total number of CDs Liam, Alex, and Michael have:

$7(9+7+11)$

$=63+49+77$

$=189.$

Therefore, the total number of CDs Liam, Alex, and Michael have is 189.
