Question

Please help !!
Answer all 6 correctly for a brainliest and also a thanks . ( and 30 points only if answered correctly otherwise will get reported ) !

Answer 1

easy

1.
Vcyliner=(h)(π)(r²)

2.
Vcone=(1/3)(h)(π)(r²)

3.
Vsphere=(4/3)(π)(r³)

4.
Vcylinder
h=16
r=d/2=8/2=4
Vclinder=(16)(π)(4²)=256π cm³, aprox 804.247 cm³

5.
h=8
r=5
Vcone=(1/3)(8)(π)(5²)=(200π)/3 cm³ aprox 209.43946 cm³

6.
r=10
Vsphere=(4/3)(π)(10³)=(4000π)/3 mi³ aprox 4188.789333 mi³
