Answer:
I think the answer is 7;
Step-by-step explanation:
All i did was subtract Q11 from all 4 of its sides;
11=4=7

Answer:
756πcm³
Step-by-step Explanation:
The volume of the solid shape = volume of cone + volume of the hemisphere.
==> 270πcm³ + ½(4/3*π*r³)
To calculate the volume of the hemisphere, we need to get the radius of the hemisphere = the radius of the cone.
Since volume of cone = 270πcm³, we can find r using the formula for the volume of cone.
==> Volume of cone = ⅓πr²h
⅓*π*r²*10 = 270π
⅓*10*r²(π) = 270 (π)
10/3 * r² = 270
r² = 270 * ³/10
r² = 81
r = √81
r = 9 cm
Thus, volume of hemisphere = ½(4/3*π*r³)
==> Volume of hemisphere = ½(⁴/3 * π * 9³)
= ½(972π)
Volume of hemisphere = 486πcm³
Volume of the solid shape
= volume of cone + volume of the hemisphere.
==> 270πcm³ + 486πcm³
= 756πcm³

Remark
I'm just going to eave a very short note and if you answer quickly in the comments, I'll come back and edit the question.
Argument
If consists of 2 sides and 2 semicircles. Without a width, there is no number to be given. We can get a formula
Fomula
Perimeter = 2*sides + 2pi *w/2
Perimeter = 2*13 + pi*W
