Answer:

D Not congruent

Step-by-step explanation:

sergejj [24]

Answer:

= $12.25$ $\pi$

Step-by-step explanation:

Given:

Length of butcher paper,(diameter of three congruent circle) = 21 inches

Means, diameter of a circle = $\frac{21}{3}$ = 7 inches

Questioned asked:

Area of one circle = ?

Solution:

Radius of a circle ,r = half of of one circle's diameter

r = $\frac{7}{2}$

= $3.5$

Area of circle = $\pi$ $r^{2}$

$3.5\times3.5$ $\pi$

= $12.25$ $\pi$

Therefore, Area of one circle == $12.25$ $\pi$

Find the balance of $7,000 deposited at 4% compounded semi-annually for 2 years

Rufina [12.5K]

Answer:

The balance will be $7,577.03.

Step-by-step explanation:

The compound interest formula is given by:

$A = P(1 + \frac{r}{n})^{nt}$

Where A is the amount of money, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per unit t and t is the time the money is invested or borrowed for.

In this problem, we have that:

$P = 7000, r = 0.04$
