We are to solve for the value of the altitude of the given cylinder which has a radius of 5 feet and a lateral area of 70pi ft². To solve this we should recall that the formula in solving the lateral area of a cylinder is Lateral Area = 2pi*r*h. The solution is shown below:
r is equal to 5 ft
lateral area = 70pi
Solving for h, we have:
70pi = 2pi*5*h
70pi / 2pi = 5h
35 = 5h
divide both sides by 5, we have:
35/5 = 5h/5
7 = h
The answer for the length of the altitude is 7 feet.
It’s 9. 9+3=12
3,6,9,12
The twice of 3 is six more than twice is nine.
Answer:
1c, 5c, 25c and 1 dollar
Step-by-step explanation:
With 4 coins of 1c : 4 cents
4 coins of 5c: 20 cents
4 coins of 25c: 1 dollar
4 coins of 1 dollar: 4 dollars
So, 4c + 20c + 1 dollar + 4 dollars = 5.24 dollars
