Answer:  A. 28.26\text{ units}^2

Step-by-step explanation:

From the given figure , it can be seen that the distance from the center of the circle to its boundary is 3 units.

Then, Radius of circle = 3 units

Area of circle is given by :-

A=\pi r^2, where r is the radius of the circle.

Put r = 3 and \pi=3.14, we get

A=(3.14) (3)^2=28.26\text{ units}^2

Hence, the area of the given circle = 28.26\text{ units}^2

A conical-shaped umbrella has a radius of 0.4 m and a height of 0.45 m. Calculate the amount of fabric needed to manufacture thi
bonufazy [111]

Answer:

The correct answer will be "0.756596 m²".

Step-by-step explanation:

The given values are:

The radius of an umbrella,

r = 0.4 m

The height of an umbrella,

h = 0.45 m

As we know,

The lateral surface of an umbrella will be:

⇒  \pi r\sqrt{r^2+h^2}

On substituting the values, we get

⇒  \pi \times 0.4\sqrt{(0.4)^2=(0.45)^2}

⇒  0.756596 \ m^2

So that the amount of fabric needed will be "0.756596 m²".

Find the area of the blue sector. Use 3.14 for pi and round to the nearest hundredth.
jeka94

Answer:

Option C 25.64\ in^{2}

Step-by-step explanation:

we know that

The area of a circle is equal to

A=\pi r^{2}

we have

r=7\ in

substitute

A=\pi(7)^{2}=49\pi\ in^{2}

Remember that

360 degrees subtends the complete area of the circle

so

by proportion

Find the area of the blue sector for an angle of 60 degrees

\frac{49\pi}{360}=\frac{x}{60}\\ \\x={49\pi*60/360

x=25.64\ in^{2}
