Answer:

42 square units is not correct because you have to find the area of the rectangle(QUTR) and the area of the triangle(RST)

Area of rectangle is 42 square units

Area of the triangle is 10.5 square units

Add both which gives you the area of the polygon QRSU - 52.5 Square units

Point Q is 6 units from Point R.

Point R is 7 units from Point T.

Point T is 3 units from Point S.

The area of polygon QRSU is 52.5 square units.

What is the volume of the cylinder?

Anna007 [38]

Answer:

B. 2010.62 ft³

Step-by-step explanation:

The formula for the volume of a cylinder is ...

V = πr²h . . . . . where r is the radius and h is the height

Filling in the numbers and doing the arithmetic, we get ...

V = π(8 ft)²(10 ft) = 640π ft³ ≈ 2010.6193 ft³ ≈ 2010.62 ft³

The volume of the cylinder is about 2010.62 ft³.

Angle θ between two vectors is given by, $\theta =cos^{-1}( \frac{u
 \cdot v}{|u||v|} )$ ; where $u \cdot 
v=-5(-4)+(-4)(-3)=20+12=32$ ; $|u|= \sqrt{ (-5)^{2} + (-4)^{2} } = 
\sqrt{25+16} = \sqrt{41}$ and $|v|=\sqrt{ (-4)^{2} + (-3)^{2} } = 
\sqrt{16+9} = \sqrt{25}=5$ .
Therefore, $\theta =cos^{-1}( \frac{32}{ 5\sqrt{41}} )=cos^{-1}0.9995=1.8^o$
