Answer:
Step-by-step explanation:
Use the formula for volume of a cone
V = 1/3 pi r^2 (h)
V = 1/3 pi 66^2 (18)
V= 1/3 pi 4356(18)
V = 1/3 pi 78408
V = 1/3 264,201.12
V = 82,067.04cm^3
Answer:
A= 168 minutes or 2 hours and 48 minutes.
B= 3 tyres
Step-by-step explanation:
There are 300 seconds in 5 minutes
The tree is 52.8 feet, since the hypotenuse is only part of the tree, you have to add 12, since then it would equal the total height of the tree.
a^2+b^2=c^2
12^2+ 39^2=c^2
144+1521= 1665
√1665
= 40.8
40.8 + 12
= 52.8 feet
Answer:
Step-by-step explanation:
total price was reduced by $ 7
let x = the total price........ x - 7
he bought 10.....and it cost him $ 130
10(x - 7) = 130
10x - 70 = 130
10x = 130 + 70
10x = 200
x = 200/10
x = 20 <====== original price
