Lilla got 21/25 meaning she only missed 4 questions which means she got a 96/100. Tim scored 41/50 meaning he missed 9 questions meaning he got a 91/100 therefore being the reason Lilla got a higher score than Tim being that she has a 96 versus his 91. Hope that helps!!!
Answer:
R = 4cm
Step-by-step explanation:
V = π(R)²h = 480π
Divide by π
(R)²h = 480
Substitute h with 30
30*(R)² = 480
Divide by 30
(R)² = 16
Square root
R = 4cm
We do not accept R= -4 because it's a length, so it must be positive.
