<u>Given</u>:

Given that the diameter of the circle is \frac{7}{2} \ cm

We need to determine the radius, circumference in terms of π and circumference using π = 3.14.

<u>Radius:</u>

The radius of the circle can be determined using the formula,

r=\frac{d}{2}

Substituting d=\frac{7}{2}, we get;

r=\frac{(\frac{7}{2})}{2}}

Simplifying, we get;

r=\frac{7}{4} \ cm

Thus, the radius of the circle is \frac{7}{4} \ cm

<u>Circumference in terms of π:</u>

The circumference of the circle can be determined using the formula,

C=2 \pi r

Substituting r=\frac{7}{4} \ cm, we get;

C=2 \pi (\frac{7}{4})

C=\frac{7}{2} \pi \ cm

Thus, the circumference in terms of π is \frac{7}{2} \pi \ cm

<u>Circumference using π = 3.14:</u>

Substituting π = 3.14 in the circumference of the circle C=\frac{7}{2} \pi \ cm, we get;

C=\frac{7}{2}(3.14)

C=10.99 \ cm

Thus, the circumference of the circle is 10.99 cm

kow [346]

Answer:

10.5 miles.

Step-by-step explanation:

If she walks 7/10 of a mile each morning, and 1, 4/10 of a mile each day, Belle walks a total of 2 1/10 of a mile each day (2.1) miles each day)

We can just multiply the amount of miles per day by 5, (2.1 x 5) and we get 10.5 miles total.
