Which shows the correct solution of the equation<br> 1/2 a + 2/3b = 50 when b=30
Lelu [443]
1/2a + 2/3(30)= 50
1/2a + 20 = 50
1/2a= 50-20
1/2a= 30
A= 30(2)
A= 60

The solution is 60.

Hope this helps!

1 liter is equivalent to a volume of 1000 cm3 (the same as 10 cm x 10 cm x 10 cm). If a beaker has a cross-section the size of t
Oksanka [162]

Answer:

Volume = \frac{220}{7}r^2

Step-by-step explanation:

Given

Height = 10cm

<em>See Attachment for complete question</em>

Required

Determine the volume of the circle

The volume is calculated as thus;

Volume = \pi r^2h

Take \pi as \frac{22}{7}

<em>So; Volume becomes</em>

Volume = \frac{22}{7} * r^2 * h

Substitute 10 for h

Volume = \frac{22}{7} * r^2 * 10

Volume = \frac{220}{7} * r^2

Since, the value of the radius is not given;

<em>The volume of the circle is:</em>

Volume = \frac{220}{7}r^2
