Answer:
S = 2π(4)(16) + 2π(4²)
So option A is correct; S = 2 pi (4) squared + 2 pi (4) (16)
Step-by-step explanation:
The formula for total surface area of a cylinder is;
Total surface Area; S = 2πrh + 2πr²
Now,we are given;
Height;h =16 inches
Radius;r = 4 inches
Thus, plugging in the values into the Area formula, we have;
S = 2π(4)(16) + 2π(4²)
The correct answer from the options given is;
S = 2 pi (4) squared + 2 pi (4) (16)
Answer:
19.20 seconds.
Step-by-step explanation:
Given:
She invited 150 friends.
But she only had 5 activities for her friends and her party only lasted 4 hours.
Question asked:
How much time will each friend get on each activity ?
Solution:
First of all convert 4 hours into seconds:-
1 hour = 3600 seconds
4 hours = 3600
4 = 14400 seconds
<u>By unitary method:</u>
150 friends get time in 5 activities = 14400
1 friend get time in 5 activities = 14400
150 = 96 seconds
That means <u>each friend get 96 seconds in all 5 activities.</u>
Each friend get time on each activity = ?
Each friend get time on 5 activities = 96
Each friend get time on 1 activity = 96
5 = 19.20 seconds
Thus, each friend will get 19.20 seconds on each activity.
