Hi I can’t help you have because half of the question is cut off......
Step-by-step explanation:
Total songs = 193
Probability of pop song = 39/193 = 0.202
1. You must apply the formula for calculate the volume of a cone and and the volume of a cylinder. Then, you must sum both volumes to obtain the volume on the figure attached.
2. Volume of the cone:
Vcone=1/3(πr²h)
π=3.14
r=4 mm/2
r=2 mm
h=3 mm
3. When you substitute the values above into the formula, you obtain:
<span>
Vcone=1/3(πr²h)
</span> Vcone=12.56 mm³
4. The volume of the cylinder is:
Vcylinder=<span>πr²h
</span>
π=3.14
r=4 mm/2=2 mm
h=2 mm
5. <span>When you substitute the values above into the formula, you obtain:
</span>
Vcylinder=25.12 mm³
6. The volume of the figure is:
Vt=Vcone+Vcylinder
Vt=12<span>.56 mm³+25.12 mm</span>³
Vt=37.68 mm³
Answer:
H. 163.3
Step-by-step explanation:
The formula for the surface area of a cone is πrl(area of the side) + π
(area of the base), where l is the slant height and r is the radius. We know that the radius is 4 and the slant height is 9, so we plug it into the equation to get π(4)(9) + 
= 36π+16π = 52π which rounds to 163.3.
Answer:
7.4 in
Step-by-step explanation:
Surface area of a cube = 6s²
(where s is the side length)
Given:
Substituting the given value into the formula and solving for s:
⇒ 328.56 = 6s²
⇒ 328.56 ÷ 6 = 6s² ÷ 6
⇒ 54.76 = s²
⇒ s = √54.76
⇒ s = 7.4 in
