den301095 [7]

Answer:

Step-by-step explanation:

Given,

Radius ( r ) = 49 cm

Height (h) = 10 cm

Volume of cone=?

Now,

Applying the formula to find the volume of cone:

$\pi \: {r}^{2} \frac{h}{3}$

Plugging the values,

$\frac{22}{7} \times {49}^{2} \times \frac{10}{3}$

$\frac{22}{7} \times 2401 \times \frac{10}{3}$

Calculate

$25153.34 \: {cm}^{3}$

Hope this helps...

Answer:

1st Question

A. 85

2nd Question

B. 71

Step-by-step explanation:

1st Question

{90 + 94 + 96 + 90} = 370/4 = 92.5

{95 + 99} = 194/2 = 97

{87 + 75 + 82 + 85} = 329/4 = 82.25

{71} = 71/1 = 71

.20(92.5) +.25(97) +.30(82.25) +.25(71) = 85.175 Rounded-up = 85

___________________________________________________

2nd Question

.10(95) +.20(80) +.50(67) +.20(60) = 71

4) Allison practices her violin for at least 12 hours per week. She practices for three fourths of an hour each

zaharov [31]

Answer:

Step-by-step explanation:

So, she practices 12 hrs per week, and already has practiced 3 hrs this week.

This means she has 9 hrs left to practice.

3/4 of an hour is one session, so to find out the number of sessions she needs, you have to do (9 hours)/(one session)

which is basically 9 / ( 3/4)

$\frac{9}{3/4}=\frac{9}{1} / \frac{3}{4} = \frac{9}{1} * \frac{4}{3} = \frac{36}{3} = 12$

She needs 12 more sessions.
