Answer: the answer is B. 235.1

Step-by-step explanation:

For the large circle the

Area = pi. • r • r

In other words,

Area = 3.14 • 10.2 • 10.2

Which equals 326.7

Then for the small circle the

Area = 3.14 • 5.4 • 5.4

Which equals 91.6

Then to find the shaded area,

326.7 - 91.6 =

235.1 cm squared

Hope this helps! :)

Three tanks are capable of holding 361,841, and 901 of the greatest vessel winch can be used to fill each one of them on exact n
daser333 [38]

Answer:

Tank which is capable of holding 1 can fill each one of the tanks an exact number of time.

Step-by-step explanation:

Three tanks are capable of holding 361,841,901

To find which tank can be used to fill each one of them an exact number of time, find HCF(361,841,901)

361=19^2\\841=29^2\\901=17(53)

Therefore,

HCF(361,841,901)=1

So, tank which is capable of holding 1 can fill each one of the tanks an exact number of time.

Suppose we wish to construct the perpendicular bisector of line segment EF. We can correctly begin by placing the compass point
julia-pushkina [17]
- to a point which is more than halfway to the point F. Then draw an arc  around the point. Next place the compass point at  F and,  keeping the same distance between the points of the compass,  draw another arc so as to intersect the first arc at 2 points above and below the line EF. Finally draw a line passing through these 2 points of intersection.  This is the perpendicular bisector of EF.

Carla's plant was 10 2/3 inches tall. Yolanda's was 8 3/4 inches tall. 
marin [14]
10 2/3 inches=32/3 inches
8 3/4 inches= 35/4 inches

Find the common denominator, in this case, 12.

128/12 inches is Carla's plant

105/12 inches is Yolanda's plant.

128/12 > 105/12. Therefore, Carla's plant is taller than Yonlanda's
