Answer:
b = 6
Step-by-step explanation:
The area of a triangle is
A = 1/2 bh
9 = 1/2 *(2h) * h
9 = h^2
Take the square root of each side
3 =h
The base is 2h
b = 2(3)
b = 6
I think it’s 4 m because diameter is 2r
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
No they don’t because they are low numbers
