The radius of a circle is 14 meters. What is the circle circumference

seropon [69]

Step-by-step explanation:

HERE,

redius of a circle (r)=14 meters.

we know that,

$\boxed{\red{\sf{circle~ circumference=2\times \pi \times r }}}$

According to the question, 

circle circumference=

$\tt{2\times \pi \times 14 }$

$\tt{2 \times \dfrac{22}{7} \times 14 }$

$\tt{2 \times \dfrac{22}{\cancel{7}} \times \cancel{14}}$

$\tt{2\times 22 \times 2 }$

$\tt{ 88~meters }$

so, the circumference of that circle is 88 meters.

PLZZ ANSWER 25 PTS RATED ATAR PROMISE TO GIVE BRAINLIEST PLZZZ ANYONE KNOW THIS???? A 154-lb person burns 420 calories per hour

Novosadov [1.4K]

Answer:

c = 420t . . . . c is calories burned; t is hours riding at 15 mph

Step-by-step explanation:

There is not enough information given to write a function rule relating all the variables to calories burned. If we assume that calories are burned at the constant rate of 420 calories per hour, then total calories will be that rate multiplied by hours:

c = 420·t

where c is total calories burned by the 154-lb person, and t is hours riding at 15 mph.

___

In general, rates are related to quantities by ...

quantity = rate · time . . . . . where the rate is (quantity)/(time period)

An rectangular water tank has a base area of 56 sq. ft. and a height of 4 ft. Find its volume in cubic feet.

ira [324]

Answer: 224 cubic feet

Step-by-step explanation: If the base of the tank is 56 sq feet in area then the dimensions could be, (2,28) (4,14) (7,8) for example. However, it doesn't really matter. It's only important that the information we know is that it is area and there are two dimensions. Since volume is determined by base x width x height, we do 56 x 4. Or using one of the factored pairs that works, for example, 8 x 7 x 4 = 224.

This is a graph of y<2x+5 what is true about point A on the graph

Ilya [14]

Answer: "Point A is a solution because it is in the shaded area

Step-by-step explanation:

When we have an inequality like the one shown in the graph, the shaded area represents the possible solutions to the inequality.

If we have a dashed line, then the points in the line are not solutions (this is the case of the symbols > and < )

If the line is solid, then the points of the line are solutions (this is the case of the symbols ≤ and ≥)

In the graph we can see that point A is inside the shaded area, then point A is a solution.

Then the correct option is:

"Point A is a solution because it is in the shaded area"
