Answer:

6π units

Step-by-step explanation:

The circumference (C) of a circle is calculated as

C = 2πr ( r is the radius )

Since we only require one half of the circumference, then

0.5C = πr

given diameter = 12 then r = 12 ÷ 2 = 6, then

arc length = π × 6 = 6π units

What is the value of x^6+y^2x 6 +y 2 x, start superscript, 6, end superscript, plus, y, squared when x=1x=1x, equals, 1 and y=11

Scrat [10]

Try 122.

<h3 />

Step-by-step explanation:

Since <em>x</em> = 1, x^6 = 1.

Since <em>y</em> = 11, 11^2 = 121.

1 + 121 = 122.

<h3 /><h3>So, the value of <em>x</em> ^ 6 + <em>y </em>^ 2 = 122.</h3><h3 />

Sally has to pay a deposit to rent a kayak of $50.00, then she is charged $7.00 per hour

solmaris [256]

Answer:

$92

Step-by-step explanation:

Since Sally plans to keep the kayak for 6 hours and it's $7 per hour we can multiply 6*7 to determine how much she will be charged for keeping the kayak.

6*7=$42

Now we add this to the original deposit of $50.

$50+$42=$92

I need help on this question please

stepladder [879]

Answer:

The question does not have value of height (in the image)

the barn in shape of a cuboid with a half cylinder.

volume of barn = volume of cuboid + volume of cylinder/2

$\text{Volume}_{barn}=lbh+\frac{\pi r^2 l}{2}$

here,

$2r = b$

b=6 m

l=10 m

so, 2r=6. thus, r=3,

$\text{Volume}_{barn}=lbh+\frac{\pi r^2 l}{2} \\ \text{Volume}_{barn}= 60\timesh+\pi \times9 \times 5$

which approximately,

141.3+60h

for storing all of the hay

141.3+60h≥600

h≥7.644

so..

check if h is less than 7.644, he would not be able to store all of the barn.

mark brainliest please.
