The answer to c plz

NikAS [45]

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

If the total area of a picture measuring 10 inches by 12 inches plus a matting of uniform width surrounding the picture is 224 s

ELEN [110]

Let
x-----------> <span>uniform width surrounding the picture

we know that
(10+2x)*(12+2x)=224-----> 120+20x+24x+4x</span>²=224
4x²+44x+120-224=0
4x²+44x-104=0

using a graph tool-----> to resolve the second order equation
see the attached figure

the solution is
x=2 in

the answer is
2 inches

What is the greatest common factor of 48, 24, and 45?

pshichka [43]

Answer:

Step-by-step explanation:

Let's write the factors:

48's factors are = 1, 2, 3, 4, 6, 8, 12, 16, 24 and 48.

24's factors are = 1, 2, 3, 4, 6, 8, 12, 24.

45's factors are =1, 3, 5, 9, 15 and 45.

The greatest number that is in all three of these lists of factors is 3!

So, 3 is the greatest common factor between all three numbers!
