Answer:

C. 31 units

Step-by-step explanation:

Circumference of a circle is the distance around the circle and is given by C = pi•d

Your circle with a point and center given has a radius of 5 because from (2,1) to (7,1) is 5 units. Radius 5 means the diameter is 10.

C = pi•10

= 3.14•10

= 31.4 using 3.14 as an approximation for pi.

Circumference is approximately 31 units.

If you have a square that has sides measuring 5 inches what is the measure of its diagonal​
Oxana [17]

Answer:

5√2 Inches

Step-by-step explanation:

By definition of a square, all it's sides are the same measurement (typically signified by the variable <em>s</em> on all sides).

In a triangle (as with a intersection from one corner to the other (diagonal), It would create a right triangle. Remember, the two leg sides are the same measurement (typically placed as 1). There is one triangle side measurement rule:

1 , 1 , √2

Plug in the corresponding numbers to the corresponding units. the 5 inches is a side (not the hypotenuse), so it belongs in the 1:

1 x 5 = 5

1 x 5 = 5

√2 x 5 = 5√2

The measurement of it's diagonal (hypotenuse) is 5√2.

225 grams of flour are needed to make 9 cakes.
Brut [27]
So basically, 9 cakes need 225 grams of flour
Therefore 1 cake needs: \frac{225}{9} = 25 grams of flour

Moreover, 20 cakes need: 20 × 25 = 500 grams of flour

500 g > 475 g

Marian does not have enough flour to make 20 cakes
