Step-by-step explanation: the way to find this answer is to add 10x3 then add 5 to that then add 25 in the end and you get 60 cents. Hope this helped!
The answer is 172.8 g.
The volume of the cube (V) is:
V = a³ (a - the side of the cube)
The density (D) <span>is quotient of mass (m) and volume (V):
D = m/V = m/a</span>³
⇒ m = D · a³
<span>
It is given:
D = 2.7 g/cm</span>³
a = 4 cm
Therefore:
m = D · a³ = 2.7 · 4³ = 172.8 g
Answer:
C
Step-by-step explanation:
The volume of the cone can be calculated using formula
![V=\dfrac{1}{3}\cdot \pi r^2 h,](https://tex.z-dn.net/?f=V%3D%5Cdfrac%7B1%7D%7B3%7D%5Ccdot%20%5Cpi%20r%5E2%20h%2C)
where h is the height of the cone, r is the base radius.
In your case, h=24 un., r=7 un. So
![V=\dfrac{1}{3}\cdot \pi \cdot 7^2\cdot 24=49\cdot 8\pi=392\pi \ un^3.](https://tex.z-dn.net/?f=V%3D%5Cdfrac%7B1%7D%7B3%7D%5Ccdot%20%5Cpi%20%5Ccdot%207%5E2%5Ccdot%2024%3D49%5Ccdot%208%5Cpi%3D392%5Cpi%20%5C%20un%5E3.)
