Answer:
47.14 in³
Step-by-step explanation:
Here is the complete question
Jenny used plastic cone shaped cups to serve punch. The cups were 6 inches in diameter and 5 inches tall. What was the volume of each cup?
Volume of a cone = 
πr²h
π = 22/7
Radius = diameter / 2 = 6 /2 = 3 inches
(1/3) x (3^2) x (22/7) x 5 = 47.14 in³
X^2 -61 =20
X^2= 81x =9 x=-9
Answer:
The length of BC would be 12.2 mm.
Step-by-step explanation:
Given,
In triangle ABC,
∠BAC = 90°,
Thus by the Pythagoras theorem,
We have,
AB = 9.6 mm and CA = 7.6 mm,
By substituting the values,
Step-by-step explanation:
37.9 equals 30+7+.9 you should try to put in number form so you know what you're dealing with
Answer:
x=7
Step-by-step explanation:
4(x-8)= -2(x-5)
4x+32= -2x+10
+2x +2x
6x-32=10
+32 +32
6x= 42
divide by 6 on both sides
x=7
