Answer:

The circumference of circle is 15.7 feet

Step-by-step explanation:

First, you have to find the radius of circle by dividing the diameter by 2 :

radius = diameter \div 2

radius = 5 \div 2

radius = 2.5 \: feet

Next, you have to substitute it into the formula of circumference, C = 2×π×r where r represents radius :

C = 2 \times \pi \times 5

let \: \pi = 3.14 \\ let \: r = 2.5

C = 2 \times 3.14 \times 2.5

C = 15.7 \: feet

Answer:

here you go :)

Step-by-step explanation:

Replace the variables with their corresponding values:

\frac{2(5+3)}{2*5}

Cancel out 2 in both numerator and denominator.

\frac{3+5}{5}

Add 3 and 5 to get 8.

\frac{8}{5}

Finally, divide 8 by 5 to get your answer:

\frac{8}{5} = 1.6

Your answer is (a) 1.6

Solve for x.<br> 5<br> 10<br> 12<br> 13
zysi [14]

Answer: B)  4 & 1/6

Nice work on getting the correct answer.

============================================================

Explanation:

x is opposite the marked acute angle

5 is opposite the corresponding acute angle

So x and 5 are proportional to each other. We can form the ratio x/5

Similarly, 10 and 12 are proportional to one another. We can form the ratio 10/12.

Set those ratios equal to each other and solve for x

x/5 = 10/12

12x = 5*10 ... cross multiply

12x = 50

x = 50/12 ...... divide both sides by 12

x = (25*2)/(6*2)

x = 25/6

x = (24+1)/6

x = 24/6 + 1/6

x = 4 + 1/6

x = 4 & 1/6 which shows why <u>choice B</u> is the answer.

Side note: 25/6 = 4.167 approximately
