Answer:
A. 69.12 in.³
Step-by-step explanation:
Volume of the crayon balloon = volume of the cone + volume of the cylinder
= ⅓πr²h + πr²h
✔️Volume of Cone = ⅓πr²h
r = ½(2) = 1 in.
h = 3 in.
Volume of cone = ⅓*π*1²*3 = 3.142 in.³
✔️Volume of Cylinder = πr²h
r = ½(2) = 1 in.
h = 21 in.
Volume of Cylinder = π*1²*21 = 65.97 in.³
✅Volume of the crayon balloon = 3.14 + 65.973 = 69.115
= 69.12 in.³ (nearest hundredth)
Answer:
6x + 1
Step-by-step explanation:
1. (10x + 3) + (-4x -2) --> sum means to add.
2. Combine like terms --> 10x - 4x = 6x; 3 - 2 = 1.
3. 6x + 1
Answer:
y-axis, x-axis, y-axis, x-axis
Step-by-step explanation:
Alright, so this problem looks a lot harder than it really is. When you flip a point across the x axis, y becomes negative, and when it is flipped across the y axis, x becomes negative. This means that if the x value changes signs it was flipped on the y axis, and vice versa.
No it's as n example of a equality
