PLEASEEEE HELP URGENT
kotegsom [21]

Answer:

7.1 cm

Step-by-step explanation:

The diagonal of a cube connects two opposite corners.

You can use the diagonal of a cube in a right triangle in which it is the hypotenuse. The legs of the triangle are a diagonal of a face and an edge.

Let the length of the edge be s.

a^2 + b^2 = c^2

s^2 + 10^2 = (\sqrt{150})^2

s^2 + 100 = 150

s^2 = 50

s = \sqrt{50}

s = 5\sqrt{2}

s = 7.1

Answer: 7.1 cm

IRINA_888 [86]

Step-by-step explanation:

step 1. The circumference (c) of a circle is the diameter of a circle x pi. c = d(pi) = 14pi.

step 2. The area (A) of a circle is the radius of a circle squared x pi. The radius of a circle is 1/2 x the diameter. A = (14/2)^2(pi) = 49pi.
