Answer:

28.26 $cm^2$

Step-by-step explanation:

The area of the quarter circle is the area of the circle / 4. Thus, the area is $\frac{\pi r^2}{4}$ = $\frac{3.14*6^2}{4}$ = 28.26 square centimeters

Answer:

28.26

Step-by-step explanation:

Volume of a Circle = 3.14 * radius * radius

---------------------------------------------------------------------

Volume of quarter of circle = (6*6*3.14)/4

= 28.26

Given that U is the centroid of triangle OPQ find PS.

o-na [289]

Answer:

PS=5.4

Step-by-step explanation:

The centroid divides each median in the ratio 2:1

If U is the centroid, then

$3.6:x+0.8=2:1$

We use ratio to obtain;

$\frac{3.6}{x+0.8}=\frac{2}{1}$

Cross multiply;

$3.6=2(x+0.8)$

Expand;

$3.6=2x+1.6$

Group similar terms;

$3.6-1.6=2x$

$2=2x$

x=1

PS=PU+US

PS=3.6+1+0.8

PS=5.4
