Solve the multi step literal equation: solve equation for A b^2A^2-3g=q

I am Lyosha [343]

Answer:

A = ± $\sqrt{\frac{q+3g}{b^2} }$

Step-by-step explanation:

Given

b²A² - 3g = q ( add 3g to both sides )

b²A² = q + 3g ( divide both sides by b² )

A² = $\frac{q+3g}{b^2}$ ( take the square root of both sides )

A = ± $\sqrt{\frac{q+3g}{b^2} }$

The area of a circle is 132.7 square cm. Find the diameter.

hram777 [196]

13 cm (approximately)

Step-by-step explanation:

Let the radius of the circle be 'r'.

Area of the circle = πr²

=> 132.7 = (22/7) r²

=> 6.5 ≈ r

Therefore, diameter = 2radius = 2(6.5) = 13 cm

V=1/3Πr^2(2r+h)

stiv31 [10]

Answer:

h= $\frac{−2.094395r3+v}{1.047198r2}$

Step-by-step explanation:

v=( $\frac{1}{3}$ (3.141593))(r2)(2r+h)

Step 1: Flip the equation.

1.047198hr2+2.094395r3=v

Step 2: Add -2.094395r^3 to both sides.

1.047198hr2=−2.094395r3+v

Step 3: Divide both sides by 1.047198r^2.

h= $\frac{−2.094395r3+v}{1.047198r2}$
