Answer:

S.A = 704 cm^2

Step-by-step explanation:

We know that the formula to find the surface area of a cone:

S.A = \pi r (r + \sqrt{h^2 + r^2} ), where "r" is the radius and "h" is the height.

Given: r = 7 cm and h = 24 cm. The value of π = 22/7

Now plug in the given values in the above formula, we get

S.A = = \frac{22}{7} *7 (7 + \sqrt{24^{2}+ 7^2 } )

S.A = 22(7 + \sqrt{576 + 49} )

S.A = 22(7 + \sqrt{625} )

S.A = 22( 7 + 25)

S.A = 22(32)

S.A = 704 cm^2

The surface area of the cone is S.A = 704 cm^2.

<h2>Hello!</h2>

The answer is: None of the options.

The correct answer is: 703.69cm^{2}

<h2>Why?</h2>

The total surface area of the cone is equal to:

TotalArea=BaseArea+LateralArea

Calculations:

tex]BaseArea=\pi*r^{2}=\pi*7^{2}=153.94cm^{2}[/tex]

LateralArea=BasePerimeter*SlantHeight/2\\BasePerimeter=2*\pi*r=2*\pi*7=43.98cm\\SlantHeight=\sqrt{height^{2}+radius^{2}  }=\sqrt{576+49}=\sqrt{625}=25

[LateralArea=43.98*\frac{25}{2}=549.75cm^{2}

So,

TotalArea=153.94cm^{2} +549.75cm^{2}=703.69cm^{2}

Have a nice day!

Is the GCF of of any two odd numbers always odd? And please an explaination or counter example
Marat540 [252]
Yes because of you find the gcf for 9 and 15, the answer would be 3 so the asnwer is still odd.

Complete the proof by providing the missing statement and reasons
Lisa [10]

Answer:

In triangle SHD and triangle STD.

\overline{SD} \perp \overline{HT}          [Side]

Since, a line is said to be perpendicular to another line if the two lines intersect at a right angle.

⇒ \angle SDH = \angle SDT = 90^{\circ}

\overline{SH} \cong \overline{ST}       [leg]               [Given]

Reflexive property states that the value is equal to itself.

\overline{SD} \cong \overline{SD}       [Leg]       [Reflexive property]

HL(Hypotenuse-leg) theorem states that any two right triangles that have a congruent hypotenuse and a corresponding congruent leg are the congruent triangles.


then, by HL theorem;

\triangle SHD \cong \triangle STD                       Proved!

Work out an estimate for the value of<br> 41.2 x 19.8<br> ——————-<br> 0.49
frez [133]

Answer:

820

Step-by-step explanation:

41.2 * 19.8 = 41 *20 = 820

41.2

In this tenth value is 2 which is less than 5. So ignore it and write the whole number alone. 41

19.8

In this tenth value is 8 awhich greater than 5. So add 1 to whole part and write.

19+1 = 20
