What is the volume of this sphere?

Natasha_Volkova [10]

Answer:

Option c. 11,488.21 cm3

Step-by-step explanation:

<u><em>The picture of the question in the attached figure</em></u>

we know that

The volume of the sphere is equal to

$V=\frac{4}{3}\pi r^{3}$

we have

$r=28/2=14\ cm$ ---> the radius is half the diameter

$\pi =3.14$

substitute

$V=\frac{4}{3}(3.14)(14)^{3}$

$V=11,488.21\ cm^3$

Mary invests £12000 in a savings account. The account pays 1. 5% compound interest per year. Work out the value of her investmen

mestny [16]

Answer:

The value of Mary's investment after two years = £12362.7

Step-by-step explanation:P = Principal / initial amountR = rate of interest per cent per yearT = number of yearsA = final amount at the end of T yearsThen:A = P*(1 + R/100)^2In our example:P = £12000R = 1.5 per cent per yearT = 2 yearsThus:A = 12000*(1 + 1.5/100)^2 = 12000*(1 + 0.015)^2 = 12000*(1.015)^2 = 12000*(1.030225) = 12362.7Value of investment after two years = £12362.7

How many cubes with side lengths of 1/2 cm does it take to fill the prism? Height: 3/2 cm Width:1 cm length: 2 cm

Irina18 [472]

Answer:

Step-by-step explanation:

If we want to cover the base of the prism having dimensions 2 cm × 1 cm with $\frac{1}{2}$ cm length of cube, then there will be (4 × 2) = 8 cubes that can occupy the base.

Width is 1 cm, so there can fit 2 cubes of length $\frac{1}{2}$ cm and length is 2 cm, where 4 cubes of length $\frac{1}{2}$ cm can fit. So, in total (4 × 2) = 8 cubes of $\frac{1}{2}$ cm length.

Now, height of the prism is $\frac{3}{2}$ cm where 3 cubes of length $\frac{1}{2}$ cm can fit.

Therefore, in total there can be (8 × 3) = 24 cubes of $\frac{1}{2}$ cm length. (Answer)
