Answer:

Option (a) is correct.

The circumference of circle is 30π inch.

Step-by-step explanation:

Given : A circle with radius 15 inch

We have to find the circumference of the given circle.

Consider the given circle

We know,

Circumference of circle = 2·π·r

given : Radius = 15 inches

Put we get,

Circumference of circle = 2·π·15 = 30π inch.

Thus, The circumference of circle is 30π inch.

The formula for finding the circumference is pi times the diameter so If your giving it in terms of pi then you're just finding the diameter which is 15

Answer:

The correct answer is:

(7s-2)+3+(s+3) = 52, or 8s+4 = 52.

Step-by-step explanation:

Since s is the son's age, "two less than seven times" the son's age would be represented by 7s-2. To represent this in 3 years, we would add 3: (7s-2)+3. In 3 years, the son's age, s, would be represented by s+3. We are told that the sum of these ages will be 52; this gives us (7s-2)+3+(s+3) = 52.

To simplify this, combine like terms. 7s+s = 8s; -2+3+3 = 4. This gives us 8s+4=52.
