Answer:

44cm

Step-by-step explanation:

Formula for circumference, C = 2πr

where r is the radius

r = C / 2π

= $\frac{88\pi }{2\pi }$

=44 cm

Answer:

approximately 44 cm

Step-by-step explanation:

The formula for circumference of a circle of radius r is C = 2π·r. Solving for r, we get:

r = ------------

2π

and in this instance, r = 88π cm / 2π, or 44 cm

Mary invests £12,000 in a savings account the account pays 1.5% compound interest per year work out the value of her investment

Lesechka [4]

Answer:

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

Step-by-step explanation:

P = Principal / initial amount

R = rate of interest per cent per year

T = number of years

A = final amount at the end of T years

Then:

A = P*(1 + R/100)^2

In our example:

P = £12000

R = 1.5 per cent per year

T = 2 years

Thus:

A = 12000*(1 + 1.5/100)^2

= 12000*(1 + 0.015)^2

= 12000*(1.015)^2

= 12000*(1.030225)

= 12362.7

Value of investment after two years = £12362.7

Whats the answer to x^3 y^0 z^-2

Elina [12.6K]

Answer:

$\frac{x^3}{z^2}$

Step-by-step explanation:

There are no given values, therefore we can't determine a definite answer. However, we are able to simplify the expression.

As we all know that any variable or number to the power of 0 is equal to 1. This means that $y^0 = 1$ .

We also know that a negative power can bring the variable down and make it a fraction. This means that $z^-^2=\frac{1}{z^2}$

Now that we got these two sorted we are able to write it in a simplified form.

Answer: $\frac{x^3}{z^2}$

The circumference of the bike tire above is 83.524 inches. What is the radius of the bike tire? (Use 3.14 for .) A. 262.27 in B.

Shtirlitz [24]

Answer:

Option <u>C. 13.3 in</u>.

Step-by-step explanation:

Here's the required formula to find the radius of the bike tire :

$\longrightarrow{\pmb{\sf{C_{(Circle)} = 2\pi r}}}$

C = circumference
π = 3.14
r = radius

Substituting all the given values in the formula to find the radius of the bike tire :

$\begin{gathered} \qquad{\longrightarrow{\sf{C_{(Circle)} = 2\pi r}}} \\ \\ \qquad{\longrightarrow{\sf{83.524 = 2 \times 3.14 \times r}}} \\ \\ \qquad{\longrightarrow{\sf{83.524 = 6.28 \times r}}} \\ \\ \qquad{\longrightarrow{\sf{83.524 = 6.28r}}} \\ \\ \qquad{\longrightarrow{\sf{r = \frac{83.524}{6.28}}}} \\ \\ \qquad{\longrightarrow{\sf{r = 13.3 \: in}}} \\ \\ \qquad \star{\underline{\boxed{\sf{\red{r = 13.3 \: in}}}}}\end{gathered}$

Hence, the radius of bike tire is 13.3 inches.

Three people divide up a large pizza. If the first person gets half and the second person gets half as much as the first person

Eduardwww [97]

So, if the first person takes half of the pizza, half of the pizza is left.
If the second person takes half of the amount the first person took, that would be a quarter of the pizza left.

TL;DR - There is 1/4 of the pizza left
