Answer:

Scott is wrong because he did not add the diameter that connects the arc

the fence is 41.12 feet. He would buy 42 feet

Step-by-step explanation:

Circumference of a semicircle = πr + d

π = pi = 3.14

d = diameter = 16

r = radius = 16/2 = 8

the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.

A radius is half of the diameter

( 3.14 x 8) + 16 = 41.12 feet

If the original quantity is 10 and the new quantity is 11, what is the percent crease?
LenKa [72]

Answer:

10 %

Step-by-step explanation:

We first find change in the quantities

Then we write the change in quantity on original quantity and multiply by 100%

This implies that,

\frac{11 - 10}{10} \times 100\%

=\frac{1}{10}\times100\%

=10\%

Therefore the percentage increase is 10%

Can someone help me
Llana [10]

3x + 4x +5x = 54   (because the perimeter = sum of its dies)

12x = 54

x = 4.5

So the 3 sides are 3*4.5 , 4*4.5 and 5*4.5

= 13.5, 18 and 22.5  units (answer)
