Answer:
Step-by-step explanation:
The volume of the cylinder is
where r is the radius of a base circle and h is the cylinder's height.
If cylinder has diameter of 8 inches, then its radius is 4 inches. The height of the cylinder is 5 inches. Thus, the volume of the cylinder is
The volume of the cone is
where r is the radius of a base circle and h is the cone's height.
If cone has diameter of 8 inches, then its radius is 4 inches. The height of the cone is 15 inches. Thus, the volume of the cone is
As you can see the cylinder and the cone have the same volume.
Answer:
7 coats
Step-by-step explanation:
they purchased 7 coats and 5 sweaters
The answer is <span>49x2 _ 84x + 36
</span>
(7x - 6)² is the square of the difference. The general formula would be:
(a - b)² = a² - 2ab + b²
In our expression (7x - 6)², a would be 7x and b would be 6:
(7x - 6)² = (7x)² - 2 · 7x · 6 + 6²
= 7² · x² - 84x + 36
= 49x² - 84x + 36
x = 1040/43 = $24.19 per day.
y = 10/43 = $0.23 per mile.
Answer:
y > 4x-8
