Answer:

≈ 30.63 cm²

Step-by-step explanation:

The shaded area is calculated by subtracting the area of the inner circle from the area of the outer circle.

outer circle has radius = 8 ÷ 2 = 4 and inner circle has radius = 5 ÷ 2 = 2.5

shaded area = πr₁² - πr₂² (r₁ is outer and r₂ is inner )

A = π (4² - 2.5²)

   = π(16 - 6.25) = 9.75π ≈ 30.63 cm²

Can someone help me? I know 1 is 90 and 5 is 90 but idk the rest
miv72 [106K]

Answer:

2 is 60 degrees, 5 is 90 degrees, 4 is 20 degrees, 3 is 30 degrees, and 1 is 90 degrees.

Step-by-step explanation:

All angles have to equal up to 90 degrees. Some you can guess, but others you might have to think about. So just look at the lines and you will see four boxes or four sections. Each have to equal up to 90 degrees, so that's what you get for those. It's kinda hard to explain, but I hope this helps, have a good day. c;

Spencer opened a savings account and deposited $10. The account pays 3.5% interest and compounds the interest monthly. How much
Angelina_Jolie [31]

Answer:

\$14.18  

Step-by-step explanation:

we know that    

The compound interest formula is equal to  

A=P(1+\frac{r}{n})^{nt}  

where  

A is the Final Investment Value  

P is the Principal amount of money to be invested  

r is the rate of interest  in decimal

t is Number of Time Periods  

n is the number of times interest is compounded per year

in this problem we have  

t=10\ years\\ P=\$10\\ r=0.035\\n=12  

substitute in the formula above  

A=P(1+\frac{0.035}{12})^{12*10}=\$14.18
