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
Answer:
A. -3
Step-by-step explanation:
(4) - (-2) = 6
(-1) - (1) = -2
6/-2
/2
-3
Answer:
12x-2
Step-by-step explanation:
You need to add 5x+1 and 7x-3.
5x+1+7x-3.
We need to organize this into common terms.
5x+7x+1-3
Now we simplify.
12x-2
That is the final answer!!

'of' in mathematics means multiplication
'is' in mathematics means equal
52% * x = 13
52/100 * x = 13
0.52x = 13
x = 13/0.52
x = 25
52% of 25 days is 13 days.
