Can someone help me with this?

Step-by-step explanation:

The formula for the volume of a sphere is V = 4/3 πr³.

Given

Volume (v) = 57ft³

$v = \frac{4}{3} \pi {r}^{3}$

$57 = \frac{4}{3} \times 3.14 \times {r}^{3}$

$57 = \frac{12.56}{3} \times {r}^{3}$

$57 = 4.19 \times {r}^{3}$

${r}^{3} = \frac{57}{4.19}$

${r}^{3} = 13.6$

$r = \sqrt[3]{13.6}$

Therefore r = 2.4 ft

I gave my answers by rounding off. so if you don't round off then it's answer is 2.3 ft

Sheila was making place-value disks. She colored 2/6 of the disks red. She colored 1/4 of the disks yellow. If she colored 40 re

Anastasy [175]

Answer:

She colored 30 yellow place value disks and 50 disks are left to color.

Step-by-step explanation:

Let total number of disks be x.

It is given that, she colored 2/6 of the disks red. She colored 1/4 of the disks yellow.

$\text{Red disks}=\dfrac{2}{6}x$

$\text{Yellow disks}=\dfrac{1}{4}x$

She colored 40 red place value disks.

$\dfrac{2}{6}x=40$

$\dfrac{1}{3}x=40$

$x=120$

It means total number of disks is 120.

$\text{Yellow disks}=\dfrac{1}{4}x=\dfrac{1}{4}(120)=30$

So, she colored 30 yellow place value disks.

Remaining disks = Total disks - Red disks - Yellow disks

$=120-30-40$

$=50$

Therefore, 50 disks are left to color.

If two figures are similar, the corresponding sides are?

otez555 [7]

<h3><u>Proportional.</u></h3>

The corresponding sides of similar figures can be equal, but if they are different in any way, they will always be proportional.

Corresponding angles, however, will always be equal.
