Answer:
86.28 ft²
Step-by-step explanation:
l = 10 ft
w = 8 ft
π = 3.14
r = ½ of 8 = 4 ft
Area of the figure = area of rectangle + area of semi-circle = 80 + 6.28 = 86.28 ft² (nearest hundredth)
Answer:
549.5
Step-by-step explanation:
For a estimate of pi we use 3.14. So 3.14x5x5x7=549.5
For a realistic answer its 549.778714378.....

ur mom reminds me of my dad lol
Step-by-step explanation:
Answer:
a = 8
r = 15%
When t = 3, y= 4.9
Step-by-step explanation:
8 represents the original amount because that's what you're increasing, so a=8.
To find your percentage, look into the parenthesis to see the decimal. We see that it's 0.15, but that's not a percentage yet, so you have to multiply it by 100. Or, moving your decimal two times to the right. Therefore, r=15%.
Now to find what the function will equal when t=3, simply plug 3 for t. I've always used a calculator for this so I'm not going to write it out (sorry). Your result should be 4.9 (this is already rounded to the nearest tenth for you).
