Answer:

Length of the minor arc AB = 5.27777777778 cm

Step-by-step explanation:

Here you would require a simple proportionality.

The ratio of the degree of the minor arc (95 degrees) over the total, 360 degrees of every circle, comparative to the length of the minor over the circumference (20 cm).

Here we can propose that the length of the minor can be equal to x.

Now let's substitute the known values:

95 / 360 = x / 20

Now cross multiply:

360 * x = 95 * 20 ⇒

360x = 1900 ⇒

x = 5.27777777778 ⇒

length of the minor arc AB = 5.27777777778 cm

The volume of a right circular cone is 2,279.64 in cubed. If the height of the cone is 18 in, what is the diameter of the cone?

Aleksandr [31]

ANSWER

A. 22 in

EXPLANATION

The volume of a cone is calculated using the formula:

$Volume = \frac{1}{3} \times \pi {r}^{2} h$

It was given that: the volume is 2,279.64 in³

The height of the cylinder is also given as: h=18 in.

We substitute, the given values into the formula to get:

$2279.64= \frac{1}{3} \times (3.14) \times {r}^{2} \times 18$

$2279.64= 18.84 {r}^{2}$

${r}^{2} = \frac{2279.64}{18.84}$

${r}^{2} = 121$

We take positive square root to get;

$r = \sqrt{121}$

$r = 11in$

Therefore the diameter is 2(11) which is equal to 22 inches.

The current average property value is two-sevenths more than last year’s average value. What was last year’s average property va

Ilya [14]

Answer:

$63350$

Step-by-step explanation:

Given that the current average property value is two-sevenths more than last year’s average value.

Let x be the last year's average property

Then we have as per the given information this year property value

= $x+\frac{2}{7} x$

Equate this to

$x+\frac{2}{7} x=81450\\9x = 7(81450)\\x = 7(9050)\\x= 63350$
