Erika needs to purchase 13 boxes, although she will have 3 more pencils than needed, 12 boxes would not be enough, in other words she will have 3 extra, but that is the only way that she will acquire the required amount.

What is the sum of the geometric series?
Dvinal [7]

Essentially this is asking you to sum the first three values of the geometric series that starts with i being 1 and has the rule of (8(\frac{1}{4})^{i-1}).

Since we must sum the first <em>three </em>geometric values we need to see what the value of i will be for the first three. The sigma notation shows us that the first i will be equal to 1. This means the second i is 2 and the third i is 3.

Knowing this you can plug in the corresponding i values into (8(\frac{1}{4})^{i-1}) and sum it all together

(8(\frac{1}{4})^{1-1}) + (8(\frac{1}{4})^{2-1}) + (8(\frac{1}{4})^{3-1})

(8(\frac{1}{4})^{0}) + (8(\frac{1}{4})^{1}) + (8(\frac{1}{4})^{2})

(8(1)) + (8(\frac{1}{4})) + (8(\frac{1}{16}))

(8) + (2) + (\frac{1}{2}))

10 + \frac{1}{2})

\frac{21}{2})

What is the volume of a right circular cylinder with a diameter of 46. 25 cm and a height of 18. 5 cm? Enter your answer in the
Sedbober [7]

The volume of the right circular cylinder is 31064.54 cm³.

What is the formula for the volume of cylinder?

Formula:

V = πr²h.............. Equation 1

Since,

V = Volume of the right circular cylinder

r = radius of the base of the cylinder

h = height of the cylinder.

We have given that,

r = 46.25/2 = 23.125 cm

h = 18.5 cm

π = 3.14

We have to calculate volume of right circular cylinder.

Therefore,

Substitute these values into equation 1

V = 3.14(23.125²)(18.5)

V = 31064.54 cm³

Therefore

The volume of the right circular cylinder is 31064.54 cm³.

Bobby and his family went to the playground. The slide is 13
Nonamiya [84]

Answer:

it would be close to 12 ft im not 100% sure though the measurements are a little off

Step-by-step explanation:

hypotenuse is 13

then you have the adjacent = 7

13^2 = 169

7^2= 49

169-49=120

the square root of 121 is 11 wich is fairly close to 120(doesnt have one because its not exact)

there is two extra feet so 11 +2 is 13 but there  was a little less then 11 so i had sid roughly around 12

brainliest, please???
