Answer:
36 (Fill 3 in the blank)
Step-by-step explanation:
Given:
Volume of a cylinder = 324 π
Height = 9 cm
The formula to find the volume of a cylinder = Base area * height.
Base is a circle. So the area of a circle = πr^2
Volume of the cylindrical pillar = πr^2 h
324 π = πr^2 . 9
πr^2 = 324 π /9
πr^2 = 36 π
The area of the base = 36 π
Thank you.
Answer:
In polynomial function f(x) = 5x² + 2x³ + 4 the leading coefficient is 5.
The leading coefficient of a polynomial is the coefficient of the leading term 5x².
Step-by-step explanation:
Answer:
A^-1:B^-1
Step-by-step explanation:
im not 100% sure but i think this is the right answer :)
5x + 2(x + 1) ≤ 23
Distribute the 2.
5x + 2x + 2 ≤ 23
Combine like terms.
7x + 2 ≤ 23
Subtract 2 from both sides.
7x ≤ 21
Divide both sides by 7
x ≤ 3
Answer: 16 inches
Step-by-step explanation:
The area of a triangle = bh/2
where b = base = unknown
h = height = 5 3/4 inches
Area = 46 inches²
Therefore, 46 = base × 5 3/4 / 2
Cross multiply
46 × 2 = base × 5 3/4
92 = base × 5 3/4
Base = 92 ÷ 5 3/4
Base = 92 ÷ 23/4
Base = 92 × 4/23
Base = 4 × 4
Base = 16 inches
