Step-by-step explanation:

We have,

Height of cone, h = 12.7 m

Circumference of base, C = 18.9 m

The base of a circular cone is circular. The circumference of circle is given by :

C=2\pi r

r is radius

r=\dfrac{C}{2\pi}\\\\r=\dfrac{18.9 }{2\pi}\\\\r=3\ m

The volume of a right circular cone is given by the formula as :

V=\dfrac{1}{3}\pi r^2h

V=\dfrac{1}{3}\times 3.14 \times 3^2\times 12.7\\\\V=119.634\ m^3

Use mental math. A resort has 380 rooms with space for 6 people. Estimate the greatest number of people who could be in these ro
Olin [163]

Answer:

6 people

Step-by-step explanation:

Since the resort has 380 rooms with space for 6 people, only 6 people can be in these rooms at the same time.

Note: It was not said that each room has space for 6 people but the hotel has space for 6 people

Irrespective of the number of rooms available, the space limit is 6, hence not more than 6 people can be accommodated.

Maury and Tyra are making phone calls to state representatives' offices to lobby for an issue. Muary can call all 120 state repr
oee [108]
Maury = 120/10 (12 calls/hour)
Tyra = 120/8 (15 calls/hour)

Together they are 27 calls per hour.
120 / 27 = 4.4444444444

So it'd take them 4.44444444 (recurring) hours to make 120 calls.

Shen’s mother gave him $10 to go buy groceries. He picked up a gallon of milk for $3.49, three pounds of oranges that cost $1.14
Vesnalui [34]

Answer:

He estimated there were about $10.40 worth of groceries

Step-by-step explanation:

You want to round the prices up to the nearest tenth and then add them all.

3.50

3.50

1.15

1.15

1.15

___

10.45

So 10.45 is closest to 10.40 and you have to remeber that this is just an estimate so it will be less because we rounded the answer up.

Hope this helps

dolphi86 [110]

Answer: 0.6 cm

Step-by-step explanation:

Given : Over the past 4 years, Grandpa Ernie's height decreased by a total of 2.4 cm.

If  the height is decreased by the same amount each year.

Then, the change in Grandpa Ernie's height each year will be =

Total decrease in height ÷ 4

= 2.4 cm  ÷  4  = 0.6 cm

Hence, the  change in Grandpa Ernie's height each year = 0.6 cm
