The circumference of a circle is C = 7.64(pi) inches. what is the length of the radius and diameter.

Answers

The exact circumference is shown there.  The exact circumference has the length of the diameter and pi.  Like,  say a diameter was 8 inches.  It would be 8(pi).

The diameter here is 7.64 inches.  A radius is half as big as a diameter,  so divide the diameter by 2.  The radius is 3.82 inches.

Hope this helps!

First of all observe that

r^6s^3=(r^2s)^3 \implies \sqrt[3]{r^6s^3}=\sqrt[3]{(r^2s)^3}=r^2s

So, we have

\log(r^5s^6\sqrt[3]{r^6s^3})=\log(r^5s^6\cdot r^2s)

We can simplify the input as

\log(r^5s^6\cdot r^2s)=\log(r^7s^7)

The logarithm of a multiplication is the sum of the logarithms:

\log(r^7s^7)=\log(r^7)+\log(s^7)

Finally, invoke the logarithm property \log(a^b)=b\log(a)

to get the final answer

\log(r^7)+\log(s^7)=7\log(r)+7\log(s)

Before a century plant dies, a tall flower stem grows from its center the flower stem grows for only two months to reach 40% of a height of 25 feet how tall is the flower stem after two months?

Answers

The number feet the flower stem grows after two months is 15 feet.

Given that, the flower stem grows for only two months to reach 40% of a height of 25 feet.

What is percentage?

Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".

Now, 40% of 25

= 40/100 × 25

= 0.4 × 25

= 10

Thus, 25-10=15

Therefore, the number feet the flower stem grows after two months is 15 feet.

50 ft because you times 20 by 40 then you divide by 100 because that is the total percent
