Please help! What is the surface area of the sphere in terms of pi? The diameter is 2

1 answer:

3 0

The surface area of ANY sphere ... EVERY sphere ... is

Area = (4 pi) x (radius)² .

All you have to do is take the radius, square it,
and multiply by 4 pi.

If you only know the diameter, the radius is half of it.

So for your sphere, the surface area is

(4 pi) x (1 unit)²

= (4 pi) x (1 square unit)

= 4 pi square units.

Express each fraction as a percent 7/20

Sergio [31]

<span>To find out what percent 7 out of 20 is, we need to ask: 7 out of 20 is how many out of 100? 5 groups of 20 make 100, so 7 out of 20 is 35 out of 100 (5 x 7 out of 5 x 20). Therefore 7/20 equals 35%, or 0.35 if we represent it as a decimal. I hope this helps</span>

You start your working career when you are 24 years old. Each month, you deposit $144 into a pension plan. You continue making d

Inga [223]

The balance, in dollars, (future value) when the pension plan earns 6% compounded monthly is <u>$372,134.19</u>.

<h3>What is future value?</h3>

The future value refers to the compounded future value of an asset, for example, a pension plan, based on a growth rate of interest for a future period.

The future value can be determined with the FV formula, table, or using an online finance calculator as follows:

<h3>Data and Calculations:</h3>

N (# of periods) = 528 months (68 - 24 x 12 months)

I/Y (Interest per year) = 6%

PV (Present Value) = $0

PMT (Periodic Payment) = $144

<u>Results:</u>

FV = $372,134.19

Sum of all periodic payments = $76,032 ($144 x 528)

Total Interest = $296,102.19

Thus, the balance, in dollars, (future value) when the pension plan earns 6% compounded monthly is <u>$372,134.19</u>.

PLEASE HELP ME WITH THIS QUESTION ITS URGENT!!!

Alex Ar [27]

Start by distributing the exponent to each of the terms in $(2u)^{3}$ . This will become $2^{3} u^{3}$ , and $2^{3} =8$ . Now, the expression is:

$\frac{2u^{3} v^{2} }{8u^{3} * u^{2} }$ .

We can now simplify the bottom to read: $8u^{5}$ because when multiplying variables raised to an exponent, we add the exponents. The expression now looks like:

$\frac{2u^{3} v^{2} }{8u^{5} }$

The 2/8 simplifies to 1/4:

$\frac{u^{3} v^{2} }{4u^{5} }$

Now, we have two u terms on the top and bottom. When dividing variables raised to an exponent, we subtract the exponents. However, since 3-5=-2, the term will be on the bottom to avoid the negative exponent. The final answer is:

$\frac{v^{2} }{4u^{2} }$

Hope this makes sense!!
