Answer:
V =1236.4 ft^3
Step-by-step explanation:
The volume of a cylinder is given by
V = pi r^2 h
The radius is d/2 =15/2 = 7.5
V = 3.14 (7.5)^2 * 7
V = 1236.375
Rounding to the nearest tenth
V =1236.4 ft^3
Answer:
x = 8
Step-by-step explanation:
6(x-8)= x- (8)
6x - 48=x - 8
6x- 48 + 48 = x - 8 + 48
6x = x + 40
6x - x = x + 40 - x
5x = 40
5x/5 = 40/5
x = 8
Hope it helps! :)
Answer:
7x21
Step-by-step explanation:
First, we need to find the length of the pool. Since it is three times as long as it is wide, it is 21 feet long (7 x 3 = 21). That way we can tell that it is 7x21, with a perimeter of 56 feet, and an area of 147 feet squared.
The degree of the polynomial is 2.
to find the degree, put the polynomial in descending order with the highest exponents in front. the highest exponent is the degree.
3x^6 - 4 (highest exponent here is 6, degree would be 6)
