Question

I've been working on the same 5 questions for 3 hours and i give up im doing anything i can at this point​

Answer 1

Step-by-step explanation:

$v = \pi \times r {}^{2} \times h \div 3 \\ = \pi \times 2 {}^{2} \times 10 \div 3 \\ = 41.8$

Answer 2

Answer:

Given that V=πr^2h/3

Where V is unknown

π=3

d=4; r=4/2=2

h=10

Substitute the values

V=3×2×2×10 ÷ 3

V= 120÷3

V= 40
