Answer:

20 Pi feet or 62.8318530718 ft

Step-by-step explanation:

Find the circumference

Pi X diameter

radius = 1/2 diameter

radius *2 = 20

20 * Pi

Answer:

10π feet, or about 31.42 feet

Step-by-step explanation:

Diameter = 2 times radius, so the radius is 5 feet.

The question is asking us for the circumference - the distance around the circle. Plug our radius into the formula.

C = 2πr

C = 2π(5)

<u>C = 10π feet = about 31.42 feet</u>

Answer:

70 - 5√10 ft²

Explanation:

Perimeter is the distance around a two-dimensional shape.

                       area of rectangle: length x width

Here given:

length: (3√2 + 4√5) ft

width: (-5√2 + 5√5) ft

Solve for perimeter:

length x width

(3√2 + 4√5) x (-5√2 + 5√5)

<u>apply distributive method</u>

(3√2)(-5√2) + (3√2)(5√5) + (4√5)(-5√2) + (4√5)(5√5)

<u>multiply</u>

-15(2) + 15√10 -20√10 + 20(5)

<u>combine</u>

-30 -5√10 + 100

<u>simplify</u>

70 - 5√10

What are the coordinates of the point on the directed line segment from (-10, -3)(−10,−3) to (2, -3)(2,−3) that partitions the s
azamat

Answer:

the coordinates of the point would be (-2.5,3)

Step-by-step explanation:

We want to split the segment from (-10,-3) to (2,-3) into segments with a ratio of 5:3. Since the y-coordinate is -3 for both coordinates, the y-coordinate of the partitioning point will be -3. The ratio of 5:3 corresponds to 5/8 of the distance between the x-coordinates of the two points. So we would be moving 5/8 of the distance from -10 to 2 for the x-coordinate, so the x-coordinate would be -10 + 5/8 (12) = -2.5. So the coordinates of the point would be (-2.5,3)

How do i solve this?
Natalija [7]

Because you know the area and that the shape is a square... if the side length is "s"... to find "s" you would say...

s²=1.69

Take the root of both sides and...

s=1.3 km

F - Irrational, -13.8
Because the negative sign is not inside of the radical, we can tell that the number is being multiplied by the negative. Thus, do the radical equation first, get the answer 13.8202... and multiply by -1 to get the answer. Also, it is irrational because it is not a perfect square.
