The formula for the circumference of a circle is C = 2πr. Plug in the given circumference and solve for the radius. C = 2πr 20= 2πr 10 = πr Use 3.14 as an approximate value for π and divide to solve. Round to the nearest tenth. r = 3.2
The area of a rectangle is equal to its length x width. This piece of land's area is thus 130 x 220, which is equal to 28,600 feet square.
Add 49 to both sides to move it to the other side of the equation and you are left with y2 = 49. Take the square root of both sides to solve for y. √49 = 7.
If a square is split in two at its diagonal, then its angles will also be bisected. A bisection of a 90 degree angle is 45 degrees. Thus, the formed triangles would have angles of 45, 45, and 90 degrees.
An obtuse angle is one which is greater than 90 degrees. Acute angles are less than 90 degrees, and right angles are exactly equal to 90 degrees.
If the triangle is isosceles, that means its two legs are equal in length, so they are both 4. In a right triangle, the two legs are the base and the height. The area of a triangle is equal to ½ bh, so the area = ½(4)(4) = 8 cm.
The volume of the container is equal to the length times the width times the height. V = lwh V = 8(12)(10) V = 960 cc2 Cubic centimeters are equal to mL, so a container with a volume of 960 cc2 can hold 960 mL.
The circumference = diameter x pi, and the diameter = circumference/pi. The diameter is found to be 1.75 miles, meaning if he had walked straight through, he would have walked 5.5 - 1.75, or 3.75 miles shorter.
If the first line is intersected and forms a 90 degree angle, then that means that all other angles are also equal to 90 degrees.
The sides of a rhombus are all equal. All four sides have a length of 10 cm each, so the perimeter is 10 + 10 + 10 + 10 = 40 cm.
If you draw out this triangle, you'll see that is a right isosceles triangle with two equal sides of 1 foot. This means that the base is 1 foot and the height is 1 foot. Using the formula for area of triangles, A = 1/2bh, we find the area is 0.5 feet squared.
Without knowing either side length, there are infinite possibilities of side lengths for a rectangle of area 24 square feet. For example, you could have one side of 480 feet, and one side be 0.05 feet, and still get an area of 24 square feet.
The diameter of a circle multiplied by pi is equal to the circumference. Thus the circumference is equal to 1.5 π, or about 4.71 feet.
Trapezoids do not need to have any angles that are equal to one another. If the two bases of a trapezoid are parallel, then it is possible to form a trapezoid with 2 triangles and a rectangle, but never 3 triangles.
We cannot add two terms that have variables with different exponents. As a result, this expression cannot be simplified.
To solve this system, we will first add the two equations together in order to eliminate the y term. This gives us 5x = 25. Solving for x, we find that x is equal to 5.
To find the distance, we use pythagoreas theorem. First calculate the distances in terms of x and y. The x difference is 3 and the y difference is 4. Then, √(32 + 42) = distance, which is 5.
