Half of a sphere is stacked on top of a cone. They both share a circular base. The radius of the circle is 6 millimeters. The he
Flauer [41]

Answer:

312π mm^2

Step-by-step explanation:

to find the volume of the figure, you have to calculate the volume of a cone and the volume of a sphere divided it by 2.

The volume of a cone is 1/3 * π * r ^ 2 * h, replacing the information:

V = 1/3 * (6) ^ 2 * (14) = 168π  mm^2

The volume of a sphere is 4/3 * π * r ^ 3, replacing the information:

V = 4/3 * π * (6) ^ 3 = 288π  mm^2

but since you only have half the sphere

V = 288π / 2 = 144π  mm^2

then the total volume is

Vt = 168π + 144π = 312π mm^2

pochemuha

Given :

Miki has 104 nickels and 88 dimes.

She wants to divide her coins into groups where each group has the same number of nickels and the same number of dimes.

To Find :

Largest number of groups she can have .

Solution :

In the given question we need to find the largest number of groups she can have i.e we have to find the LCM of 104 and 88 .

Now , factorizing both of them , we get :

104=1\times 2\times 2\times 2\times 13

88=1\times 2\times 2\times 2\times 11

Form above , we can say that common factors are :

HCF=2\times 2\times 2=8

Therefore , the largest number of groups she can have is 8 .

Hence , this is the required solution .

JKL is similar to PQR

so they want PR 

JKL is similar to PQR

So PR is similar to JL

And they also give us the sides KL and QR

JKL is similar to PQR

Both of those sides are similar, so we can form a proportion.

\sf { \frac{PR}{JL} =  \frac{QR}{KL} }

Plug in the numbers:

\sf { \frac{PR}{6} = \frac{15}{9} }

Cross multiply:

\sf{ PR \times 9 = 6 \times 15}

Isolate PR

\sf{ PR = \frac{6 \times 15}{9}}

Simplify it

\sf{ PR = 10}

So your final answer is

\boxed{\bf{10 centimeters}}

A picture frame is 4 inches taller than it is wide and has an area of 192 square inches. What are the dimensions of the picture
Masteriza [31]

Answer: width is 12, length is 16

Step-by-step explanation:

A= l*w

l=w+4

A=w(w+4)

A=192\\192=w^{2} +4w\\0=w^{2} +4w-192

factor

(w+16)(w-12)

w= -16 or w=12

width is 12, length is 16

KIM [24]

Answer:

45

Step-by-step explanation:

Subtract $34.99 from $40 to figure out how much money you have left for text messages.  

You have $5.01 left and you divide that by $0.11 (cost for each text).  Your answer is 45.5454.  Since you can’t send 1/2 a text, your answer is 45.
