When the radius of a sphere is doubled, what is the resulting change in volume? A) The original volume is doubled. B) The origin
kobusy [5.1K]

Answer:

C

Step-by-step explanation:

The volume (V) of a sphere is calculated using the formula

V = \frac{4}{3}πr³

If the radius is doubled, that is r = 2r , then

V = \frac{4}{3}π (2r )³

(2r)³ = 8r³, thus the volume is multiplied by 8

Jimmy loaded three bags of sand into his wheelbarrow. The bags weighed 24
Rudik [331]
The whole numbers add up to 100. So now we are left with 1/2 or 0.5, 3/5 or .60, and 1/8 or .125. Those add up to 1.225 so the amount of sand in pounds in the wheelbarrow is 101.225. Hope I helped! If you have any questions just leave a comment.

If the area of a circle is 36pi, what is the circumference
lord [1]

Answer:

113.1cm^2

Step-by-step explanation:

We know the area for a circle is pi * r^2, where r is the radius. We know the diameter, so all we need to do to find the radius is half the distance of the diameter, which would then be 6 cm. We plug in 6 as r, we get 36pi cm^2 as our exact answer. And a good approximation would be 113.1 cm^2.

Two adults and 9 students cost $50 to attend
rjkz [21]

Answer:

The cost of tickets for a play is $3.00 for adults and $2.00 for children. 350 tickets were sold and $950 was collected. How many tickets of each type were sold?

Let x = number of $3 tickets

Let y = number of $2 tickets

Total = quantity × value

Step-by-step explanation:

x + y = 350                    (equation 1)

3x + 2y = 950                 (equation 2)

Use Substitution Method

Isolate variable x in equation 1

x = 350 – y                     (equation 3)

Substitute equation 3 into equation 2

3(350 – y) + 2y = 950

1050 – 3y + 2y = 950

3y – 2y = 1050 – 950

y = 100

Substitute y = 100 into equation 1

x + 100 = 350

x = 250

Answer: 250 $3 tickets and 100 $2 tickets were sold.

Ms. Masse's biology class is conducting an experiment
olga_2 [115]
2 + 2 + 2 + 2 + 2 = 10
Five days

2 + 2 + 2 + 2 + 2 + 2 + 2 = 14
Full week

10 x 2 = 20

14 x 2 = 28

The bacteria will double every day for a total of 20/28 bacteria on the last day.
