The radius of the circle is 8 inches when the sector of a circle has an area of 104pi/9 square inches.

A sector is said to be a part of a circle made of the arc of the circle along with its two radii. It is a portion of the circle formed by a portion of the circumference (arc) and radii of the circle at both endpoints of the arc.

Radius of a circle is the distance from the center of the circle to any point on it's circumference.

Area of a sector = [tex]\frac{\theta}{360} \pi r^2[/tex]

[tex]\text{Given area = }\frac{104\times \pi}{9}=\frac{65}{360}\times \pi r^2\\\\\frac{104}{9}=\frac{65}{360} \times r^2\\\\r^2=\frac{37440}{585}\\\\r=8.001[/tex]

Hence, option b is correct, that is the radius of the circle is 8 inches.

Answer:

5.8 * [tex]10^{-7}[/tex]

Step-by-step explanation:

Move the decimal so there is one n zero digit to the left of the decimal point. The number of decimal places you moved will be the exponent on the 10. If the decimal moves to the right, the exponent will be negative. If it moves to the left, the exponents will be positive.

Answer:

10 feet 5 inches long

Step-by-step explanation:

Answer:

48π

Step-by-step explanation:

Given that,

The radius of the sphere is increasing at a rate of 3cm/minute, [tex]\dfrac{dr}{dt}=3\ cm/minute[/tex]

The volume of a sphere is given by :

[tex]V=\dfrac{4}{3}\pi r^3[/tex]

Differentiating both sides wrt t.

[tex]\dfrac{dV}{dt}=\dfrac{4}{3}\pi \times 3r^2\times \dfrac{dr}{dt}\\\\=4\pi r^2\times \dfrac{dr}{dt}[/tex]

Put r = 2 cm and dr/dt = 3 cm/minute

So,

[tex]\dfrac{dV}{dt}=4\pi r^2\times \dfrac{dr}{dt}\\\\\dfrac{dV}{dt}=4\pi \times 2^2\times 3\\\\\dfrac{dV}{dt}=48\pi[/tex]

Hence, the correct option is (a) "48π".

Answer:

At the end of that period, 3,276,800 tonnes of fish could be caught in the North Sea.

Step-by-step explanation:

Given that 8 million tonnes of fish were caught in the North sea in 2005, if the catch is reduced by 20% each year for four years, to determine what amount can be caught at the end of this time the following calculation must be performed :

100 - 20 = 80

Year 0 = 8 million

Year 1 = 8 x 0.8 = 6.4 million

Year 2 = 6.4 x 0.8 = 5.12 million

Year 3 = 5.12 x 0.8 = 4,096 million

Year 4 = 4.096 x 0.8 = 3.2768 million

Thus, at the end of that period, 3,276,800 tonnes of fish could be caught in the North Sea.

Answer:

She can buy 13 bananas

Step-by-step explanation:

She has 11.75 and each banana costs .89

Start by dividing 11.75/.89 = 13.20

She will be able to buy 13 bananas total since she cannot buy a portion of a banana (0.2) so she will just have some leftover change.

Answer:

The mean length of these 12 people's big finger is of 7.85 cm.

Step-by-step explanation:

Mean value:

Sum of the values of all observations divided by the number of observations.

In this question:

9 + 3 = 12 total observations

Sum:

[tex]9*6.8 + 3*11 = 94.2[/tex]

So

[tex]M = \frac{94.2}{12} = 7.85[/tex]

The mean length of these 12 people's big finger is of 7.85 cm.
