Find the exact length of the third side. 51

Nesterboy [21]

Answer:

Step-by-step explanation:

You can use the Pythagorean Theorem to solve this:

$a^{2} + b^{2} = c^{2}$

The legs of the triangle are put into either a or b and the hypotenuse is put into c. In this case, they've already given you the hypotenuse, but now you need to find the leg:

$45^{2} + b^{2} = 51^{2}$

2025 + $b^{2}$ = 2601

Subtract 2025 from both sides:

2025 + $b^{2}$ = 2601

-2025 -2025

_____________

$b^{2}$ = 576

Square root:

$\sqrt{b^{2} } = \sqrt{576}$

b = 24

Find the circumference and area of a circle with a diameter of 22 inches.

Katyanochek1 [597]

Answer:

$Circumference=22\pi\;inches \\\\Area =121\pi \;inches^2$

Step-by-step explanation:

Diameter of the circle= $22\;inches$

$Radius=\dfrac{22}{2} =11\;inches$

Circumference of a circle:

$=2\times \pi \times r$

$=2\times \pi \times 11\\\\=22\pi \;inches$

Area of the circle:

$=\pi \times r^2$

$=\pi \times 11\times 11\\\\=121\times \pi \\\\=121\pi \;inches^2$
