1)V=πR².H==> 323.5 x πx7²xh==>323.5=49π.h


h=323.5/49π==> h=2.101 in


2) Horizontal rectangular prisma: V₁=3x8x5 = 120 cm³
    Vertical rectangular prisma    :  V₂=2x5x6 = 60 cm³
TOTAL VOLUME =V₁+V₂ =120+60=180 cm³

AS we know that:

V=SA*h

And we have the volume and we can calculate the SA,,,

So that, we can conclude:
h= \frac{V}{SA} = \frac{323.5}{\pi (7)^2} =2.1015~~in

Are you satisfied?

Choose all values of a that make the following equation true: 3/4 = a/36.
Gekata [30.6K]

9514 1404 393

Answer:

  B, D

Step-by-step explanation:

The equation can be solved by multiplying by 36.

  3/4 = a/36

  a = 36(3/4) = 108/4 = 27

The listed values that make the equation true are 27 and 108/4.

If PQ is tangent to circle R at point Q and PS is
Murljashka [212]

Answer:

Perimeter of the quadrilateral PQRS is 25 units

Step-by-step explanation:

From the figure attached,

PQ is a tangent to the given circle so m∠PQR = 90°

Now we apply Pythagoras theorem in the ΔPQR,

PR² = PQ² + QR²

(PT + TR)²= PQ² + 5²

(4 + 5)² = PQ² + 25

81 = PQ² + 25

PQ = √(81 - 25)

     = √56

     ≈ 7.5 units

PQ ≅ PS ≅ 7.5 units

[Since measures of tangents drawn from a point to a circle are always equal]

Perimeter of PQRS = PQ + QR + RS + PS

                                = 7.5 + 5 + 5 + 7.5

                                = 25 units

Therefore, perimeter of the quadrilateral PQRS is 25 units.
