Answer: 94.24 feet.


Step-by-step explanation:

1. To solve this exercise you must apply the formula for calculate the perimeter of a circle, which is shown below:

P=2r\pi

Where r is the radius of the circle.

2. You can calculate the radius of the circle by dividing the diameter by 2, as following:

r=\frac{30ft}{2}\\r=15ft

3. Substitute this value into the formula. Then, you obtain that the result is:

P=(2)(15ft)(\pi)\\P=94.24ft

Using the distributive property to find the product (y — 4)(y2 + 4y + 16) results in a polynomial of the form y3 + 4y2 + ay – 4y
tatiyna
If you would like to find the value of a in the polynomial, you can do this using the following steps:

(y - 4)(y^2 + 4y + 16) = y^3 + 4y^2 + 16y - 4y^2 - 16y - 64 = y^3 + 4y^2 + ay - 4y^2 - ay - 64

a = 16

The correct result would be 16.

Can someone help me with this plsssss
cupoosta [38]

Answer:

15 cm

Step-by-step explanation:

Given:

The two cylinders shown in the figure are similar to each other.

Therefore, when two figures are similar their measures are in proportion.

So, radius and height of both the cylinders are in proportion.

Radius of both the cylinders are 2 cm and 5 cm respectively. Height of the smaller cylinder is 5 cm. Now,

\frac{2}{6}=\frac{5}{x}

Doing cross multiply, we get:

2x=6\times 5\\2x=30

Dividing both sides by 2, we get:

\frac{2x}{2}=\frac{30}{2}\\x=15\ cm

Therefore, the height of the larger cylinder must be 15 cm in order to make both the cylinders similar to each other.
