Find the volume of the cone shown, if r=8 cm and AC=AB=17 cm

Papessa [141]

Answer:

1005.3 cm³

Step-by-step explanation:

The radius of the cone (r) is 8 cm and the slant height is AC = AB = 17 cm.

Therefore, the height of the cone (h) will be given by $\sqrt{17^{2} - 8^{2}} = \sqrt{225} = 15$ cm.

We have to calculate the volume of the cone.

Therefore, the volume of the cone will be given by $\frac{1}{3}\pi r^{2}h$

= $\frac{1}{3} \times \frac{22}{7} \times 8^{2}\times 15$

= 1005.3 cm³ (Answer)

If collecte 63 cans which is 21%. How many cans are 46%. And how many is 33% ?

EleoNora [17]

If 63 cand are 21% we must find out what 1% is
To do that we must divide 63 by 21
63/21 = 3
So 1%=3 cans
To find out what a percentage equals we must times it by 3
46 * 3 =138 cans
33*3 = 99 cans
Hope this helps :)

The ratio of the number of Miki's stickers to the number of Ken's

Lera25 [3.4K]

Answer:

Miki had 288 stickers and Ken had 252 stickers.

Step-by-step explanation:

This question is solved using a system of equations.

I am going to say that:

Miki has x stickers.

Ken has y stickers.

The ratio of the number of Miki's stickers to the number of Ken's stickers was 8:7.

This means that $\frac{x}{y} = \frac{8}{7}$ , that is: $7x = 8y$ , or $x = \frac{8y}{7}$

After Miki gave Ken 18 of her stickers, they had the same number of stickers.

This means that:

$x - 18 = y + 18$

$x - y = 36$

Since $x = \frac{8y}{7}$

$\frac{8y}{7} - y = 36$

$\frac{8y}{7} - \frac{7y}{7} = 36$

$\frac{y}{7} = 36$

$y = 36*7 = 252$

And

$x - y = 36$

$x = 36 + y = 36 + 252 = 288$

Miki had 288 stickers and Ken had 252 stickers.
