Answer:
It’s the first one trust me
Step-by-step explanation:
Okay so all you have to do is find the Area of each shape, then add them together. Starting with the square. Your formula is A=s4 All you have to do is plug in your number. A=26(4) Now solve. A=104. Now we have to find the area of a semicircle. Your formula is ((3.14)r squared)(.5) To find the radius (r) you divide the diameter by 2, so 26/2=13 Now all you have to do is plug in your numbers. (3.14)(13 squared)(.5) (3.14)(169)(.5)
(530.66)(.5) Your final answer is: 265.33 inches squared
Answer:
1/2
Step-by-step explanation:
When given two points, we can find the slope by
m = (y2-y1)/(x2-x1)
= (1-0)/(-3- -5)
= (1-0) / (-3+5)
= 1/2
