Answer:

5 $\pi$ +40

Step-by-step explanation:

perimeter of circle=2 $\pi$ r

so 5 is r(radius)

so 10 $\pi$ , but since it’s semicircle, you have to divide by 2, so

5 $\pi$

perimeter of rectangle=15+10+15 because you don’t count the inside, so that equals 40

so 5 $\pi$ +40

In a right-angled triangle, the hypotenuse is 113 and a leg is 112.

melomori [17]

Answer: 15

Step-by-step explanation: Use the formula: $a^{2}+b^{2}=c^{2}$

Remember $c^{2}$ should always be the hypotenuse or the longest side.

$112^{2}+b^{2}=113^{2}$ ---> evaluate the exponents

$12544+b^{2}=12769$ ----> subtract 12544 to the other side

$b^{2}=225$ ---> take the square root of both sides

$b=15$
