Solve for h:V = π h r^2
V = h π r^2 is equivalent to h π r^2 = V:π h r^2 = V
Divide both sides by π r^2:
Answer: h = V/(π r^2)
Answer:
of Example 6
5 and 14
Step-by-step explanation:
IN EXAMPLE 6
Opposite angles are equal so you equate the first one like this
3x + 20 = 10x - 15
15 + 20 = 7x
35/7 = x
x = 5
In next question b
It is a straight line thus it's 180°
so 4n + 22 +8n -10 = 180
12n + 12 = 180
12n = 180 - 12
n =168÷ 12
n = 14
Answer:
2 i believe
Step-by-step explanation:
Answer: The required value of y is 22.
Step-by-step explanation: We are given the following function of a and b :

We are to find the value of y when a = 1 and b = 2.
To find the required value of y, we need to substitute the values of a and b in equation (i).
From (i), we get

Thus, the required value of y is 22.
Answer:
40
Step-by-step explanation:
because if you do 400 divided by 10, it gives you 40
