an isosceles triangle has two twin sides, stemming from a vertex.

now, the midsegment of any triangle, is half the length of the parallel base, or namely the base itself is twice as long as the midsegment, check the picture below.

so, we know the midsegment is 4, therefore the parallel base of it will be 8.

we know its perimeter is 20, and we also know the twin sides are, well twins, let's say they're "a" units long.


\bf \stackrel{base}{(8)}+\stackrel{twin~sides}{(a+a)}=20\implies 8+2a=20\implies 2a=12 \\\\\\ a=\cfrac{12}{2}\implies \boxed{a=6}

Answer: 32.35 cm^2

Step by step:

Find the area of the rectangle first.

A= L • W
A= 11 • 4.2
A= 46.2 cm^2

Then find the area of the circle. The formula is A= pi (r)^2. The diameter of the circle is 4.2 cm because looking at the width of the rectangle it fits into the circle as well.

Half of the diameter is 2.1 cm which is the radius.

A= pi (r)^2
A= pi (2.1)^2
A= pi (4.41)
A= 13.85 cm^2

Then you would subtract 13.85 from 46.2 to find the shaded portion.

Hope this helps :))

What is the gcf of 30x^2 and 66x^5?
pantera1 [17]

Answer:

6x^2

Step-by-step explanation:

Express as product of prime factors.

30x^2=2\times 3\times 5\times x^2

66x^5=2\times 3\times 11\times x^5

The greatest common factor is the product of the least powers of the common factors.

The GCF is

2\times 3\times x^2=6x^2

dybincka [34]

9514 1404 393

Answer:

  104π in² ≈ 326.7 in²

Step-by-step explanation:

Put the given numbers in the surface area formula for a cylinder.

  SA = 2πr(r +h)

  SA = 2π(4 in)(4 in +9 in) = 104π in² ≈ 326.7 in²
