4/7 of 28 is essentially (4/7)*28, or (4*28)/7, which simplifies to 112/7, to 16.

Scott wants to buy fencing to place around a semicircular rock garden The diameter of the semicircle is 16 feet Using 3.14 for p

Pavel [41]

The diameter of the semicircle is 16 feet.

He calculates that he needs to buy abut 25.12 feet of fencing.

To find amount of fencing we find the circumference of semicircle

Circumference of semicircle = $\frac{1}{2}\pi d+d$

Where d is the diameter of the circle

d= 16 given and value of pi is 3.14

Circumference of semicircle = $\frac{1}{2}*3.14*16+16$

=25.12 + 16 = 41.12 feet

Scott's calculation was wrong because he forgot to add the diameter d

Circumference of circle is half way of circle plus the diameter of circle.

Correct amount of fencing = 41.12 feet

FORMULA:

Volume of cylinder = πr²h
Volume of sphere = 4/3πr³

ANSWER:

Volume of capsule = 4/3πr³ + πr²h

πr²(4/3r + h)

3.14 × 2²(8/3 + 5.6)
3.14 × 4(2.6 + 5.6)
12.56(8.2)
102.99 or 103 rounded.

Now, Density = 0.7mg/mm³

0.7/103
0.00679mg
