Answer:
4.14
Step-by-step explanation:
Answer:
754 inches³
Step-by-step explanation:
The equation for the volume of a cylinder is V = π*r²*h.
So you have d = 8 (meaning r = 4) and h = 15. Substitute in those values into the equation and you'll get V = π*4²*15 = 753.98, which rounds to 754 inches³
Answer:
i 100% do not know
Step-by-step explanation:
Answer:
A
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
Given (h, k) = (0, - 7) and r = 11, then
(x - 0)² + (y - (- 7))² = 11², that is
x² + (y + 7)² = 121 → A
Answer:
1). 25% percentage increase
2). 75% percentage decrease
Step-by-step explanation:
1.
Amount of change =30-24=6
Original amount = 24
This means there is a percentage increase of 25%
2.
Amount of change =4-16=-12
Original amount=16
This means there is a percentage decrease of 75%
