Tan 45°= 15/x
x= 15/tan 45°
x= 15

y= $\sqrt{15^2+15^2} =15 \sqrt{2}$

The circumference of a circle is 11pi inches. What is the area, in square inches, of the circle? Express your answer in terms of

Eva8 [605]

$\bf \textit{circumference of a circle}\\\\ C=2\pi r~~ \begin{cases} r=radius\\[-0.5em] \hrulefill\\ C=11\pi \end{cases}\implies 11\pi =2\pi r\implies \cfrac{11\pi }{2\pi }=r\implies \boxed{\cfrac{11}{2}=r} \\\\[-0.35em] ~\dotfill\\\\ \textit{area of a circle}\\\\ A=\pi r^2\qquad \qquad \implies A=\pi \left( \cfrac{11}{2}\right)^2\implies A=\pi \left( \cfrac{11^2}{2^2}\right)\implies A=\cfrac{121\pi }{4}$

The legs of a right triangle are 5 units and 15 units. What is the length of the hypotenuse?

Varvara68 [4.7K]

To find the answer you have to use pythagorean theorem;

a² + b² = c² where a and b are the legs and c is the hypotenuse.

5² + 15² = c²

25 + 225 = c²

250 = c²

√250 = √c²

√250 = c

hope this helps, God bless!
