Answer:

The radius of the cylinder and sphere is 2.48 cm and the volume of the sphere is 64 cm³

Step-by-step explanation:

Let's review the information given to us to answer the question correctly:

Volume of a cylinder = π * r² * h

π * r² * h = 48

r² * h = 48/3.1416

r² * h = 15.28

r = 2.48 cm, h = 2.48 cm

Now, we can calculate the volume of the sphere this way:

Volume of the sphere = 4/3 * π * r³

Volume of the sphere = 4/3 * π * 2.48³

Volume of the sphere = 4/3 * π * 15.28

Volume of the sphere = 1.33 * 3.1416 * 15.28

Volume of the sphere = 64 cm³

1.) A 20° sector in a circle has an area of 21.5π yd².

a_sh-v [17]

Part 1) A 20° sector in a circle has an area of 21.5π yd².

What is the area of the circle?

we know that

the area of a circle represent a sector of $360$ degrees

so by proportion

$\frac{21.5\pi }{20} =\frac{x}{360} \\ \\ x*20=360*21.5\pi \\ \\x=(360*21.5*3.14)/20\\ \\x= 1,215.18\ yd^{2}$

therefore

the answer part 1) is

The area of the circle is $1,215.18\ yd^{2}$

Part 2) What is the area of a sector with a central angle of 3π/5 radians and a diameter of 21.2 cm?

we know that

the area of the circle is equal to

$A=\pi r^{2}$

where

r is the radius of the circle

in this problem we have

$Diameter=21.2\ cm\\ r=Diameter/2\\r=21.2/2\\r= 10.6\ cm$

Find the area of the circle

$A=\pi r^{2}$

$A=\pi*10.6^{2}$

$A=352.8104\ cm^{2}$

Find the area of the sector

we know that the area of the circle represent a sector of $2\pi$ radians

by proportion

$\frac{352.8104}{2\pi }=\frac{x}{(3\pi/5)} \\\\x*2\pi=(3\pi*352.8104)/5\\ \\x= 105.84\ cm^{2}$

therefore

the answer part 2) is

the area of the sector is

$105.84\ cm^{2}$

Find the area of the shaded sector.

Vladimir [108]

Given that,

Radius of the circle, r = 8.91 cm

Angle, $\theta=81^{\circ}$

To find,

The area of minor sector.

Solution,

The formula for the area of minor sector is given by the formula as follows :

$A=\dfrac{\theta}{360}\times \pi r^2\\\\A=\dfrac{81}{360}\times \pi \times (8.91)^2\\\\A=56.11\ \text{cm}^2$

So, the area of the shaded sector is $56.11\ \text{cm}^2$ .
