The area of the vase lies between the area 135\ cm^2 and 155\ cm^2 will be 153.86\ cm^2.

<h3>What will be the area?</h3>

As we know that the area of the circle is given by the formula

A=\pi r^2

So now from the question, we will find the radius for both the given areas.

Radius for the first area

r=\dfrac{A}{\pi} =\dfrac{135}{\pi} =6.56\ cm

Radius for the second area

r=\dfrac{A}{\pi} =\dfrac{155}{\pi} =7.03\ cm

Now we can see the range of the radius lies

6.56\leq r\leq 7.03

The radius must be r=7 cm lie between two quantities.

Then the area at r= 7cm will be

A=\pi r^2

A=\pi\times 7^2=153.86\ cm^2

Thus the area for the vase will be A=153.86\ cm^2 ar radius r= 7 cm

frozen [14]

Answer:

20

Step-by-step explanation:

Sonya has 5 sandwiches.she cuts each sandwich into fourths

1 sandwich divided into four parts

four parts = ¹/₄

1/¹/₄= 1x ⁴/₁= 4

so 1 sandwich divided into four parts is 4

so if 1 is divided into four parts is 4

5 will 4 x 5 = 20

so it means there will 20 of ¹/₄ sandwich

Harry is making cookies. He needs 1 3/4 cups of flour for one batch, but he wants to make 1 1/2 batches. Write an equation that
Andrei [34K]

Answer: 1 3/4 × 1 1/2

Step-by-step explanation:

Since Harry needs 1 3/4 cups of flour for one batch of cookies, but he wants to make 1 1/2 batches, the equation that can be used to find how many cups of flour Harry will need will be:

= (1 3/4 / 1) × 1 1/2

= 1 3/4 × 1 1/2

Therefore, to make 1 1/2 batches, the cups of flour needed will be:

= 1 3/4 × 1 1/2

= 7/4 × 3/2

= 21/8

= 2 5/8 cups of flours.
