Answer:

A) 60π cm³

Step-by-step explanation:

Given:

The<u> radius </u>of the base of a metallic rod is<u> 2 centimetres</u>, and its<u> height is 15 centimetres.</u>

Question asked:

What is the<u> volume </u>of this cylinder?

<u>Solution</u>:

As we know''

Volume\ of\ cylinder=\pi r^{2} h

                                =\pi \times2\times2\times15\\ \\ =60\pi

Therefore, the volume of this cylinder will be 60\pi\ cm^{3}

A cylinder has a radius of 14 m and a height of 6 m. What is the exact volume of the cylinder? 84π m³ 168π m³ 504π m³ 1176π m³
murzikaleks [220]

Answer:

1176π m³

Step-by-step explanation:

The formula for the volume of a cylinder is:

V = πr²h

Let's substitute the values given into this equation:

V = πr²h

V = (π)(14²)(6)

Solve:

V = (π)(14²)(6)

V = (π)(196)(6)

V = 1,176π

Therefore, the volume of the cylinder is 1176π cubic meters.

Find how much interests $15000 earns in 2 years in a certificate of deposit paying 7.5% interest compounded quarterly the intere
Klio2033 [76]

Answer:

Step-by-step explanation:

Initial amount deposited in the certificate of deposit is $15000 This means that the principal so

P = 15000

It was compounded quarterly. This means that it was compounded 4 times in a year. So

n = 4

The rate at which the principal was compounded is 7.5%. So

r = 7.5/100 = 0.075

It was compounded for 2 years. So

t = 2

The formula for compound interest is

A = P(1+r/n)^nt

A = total amount in the account at the end of t years. Therefore

A = 15000 (1+0.075/4)^4×2

A = 15000(1.01875)^8 = $17403

The interest would be

17403 - 15000 = $2403
