4. 9d - 5 = 4 What does d = 5. 6-3w=-27 what does w = 6. -4= q/8-19 what does q =

trapecia [35]

Answer:

4) d = 1

5) w = 11

6) q = 120

Step-by-step explanation:

4) $9d - 5 = 4$

Adding 5 on both the sides ,

$= > 9d - 5 + 5 = 4 + 5$

$= > 9d = 9$

Dividing both the sides by 9 ,

$= > \frac{9d}{9} = \frac{9}{9}$

$= > d = 1$

5) $6 - 3w = - 27$

Substracting 6 from both the sides ,

$6 - 3w - 6 = - 27 - 6$

$= > - 3w = - 33$

Dividing both the sides by -3 ,

$= > \frac{ - 3w}{ - 3} = \frac{ - 33}{ - 3}$

$= > w = 11$

6) $- 4 = \frac{q}{8} - 19$

Adding 19 on both the sides ,

$\frac{q}{8} - 19 + 19 = - 4 + 19$

$= > \frac{q}{8} = 15$

Multiplying both the sides by 8 ,

$= > \frac{q}{8} \times 8 = 15 \times 8$

$= > q = 120$

Radius= 4cm. find the area and diameter of the circle

Bezzdna [24]

<h3>given:</h3>

radius= 4 cm

the area and the diameter of the circle.

<h3>solution:</h3><h3>diameter:</h3>

$d = 2r$

$d = 2 \times 4$

$d = 8 \: cm$

therefore, the diameter of the circle is 8 centimeters.

$a = \pi {r}^{2}$

$a = \pi \times {4}^{2}$

$a = 50.26548 \: {cm}^{2}$

$a = 50.27 \: {cm}^{2}$

hence, the area of the circle is 50.27 square centimeters.
