If the exact length is s, you have
.. s = r*θ . . . . θ = π/2
.. r = s/θ
.. r = 2s/π

Fill in the exact length for "s" in the formula and compute to find the radius.

Which is the length of the hypotenuse of the triangle?​
Pepsi [2]

Since this is a right triangle, we can use the Pythagorean Theorem, which states a² + b² = c² in a right triangle.

Plugging our numbers in, we get:

(12)² + (35)² = c²

From there, we can square the numbers.

(144) + (1225) = c²

Then, we can add them together to find the sum;

(1369) = c²

And finally, we can find the square root of both sides.

(37) = c

Therefore, 37 is the answer and your answer choice is correct.

7/10 - 1/2 whats the answer
Serjik [45]
To find the answer, we can use expansion to turn the fraction’s denominator to be the same:

1/2
= 1×5 / 2×5
=5/10

We can then proceed to find the answer:

7/10 - 5/10
= 2/10
= 1/5

Therefore the answer is 1/5.

Hope it helps!
