Recall the formula for the area of a trapezoid, A=1/2h(a+b) , where h is the height and a and b are the lengths of the parallel
Gekata [30.6K]

Answer:

The area of the trapezoid is 40 square inches

Step-by-step explanation:

Here, we want to find the area of the given trapezoid

Mathematically, we apply the formula for the area

In this case, a will be 10, b will be 6 and h will be 5

Substituting these values, we have that ;

A = 1/2(10 + 6)5

A = 1/2(16)(5)

A = 40 square inches

Please really need the correct answer for this or I'll fail algebra 3
trapecia [35]

Answer:

4\pi

Step-by-step explanation:

S = Arc Lenth

θ = Radians

R = Radius

S = θR

So, now that we understand the formula, we will convert 72° into radians by introducing the equation x*\frac{\pi }{180}, x = 72

S =  72*\frac{\pi }{180} * R

given that R = 10

S = \frac{72*10*\pi }{180}

S = \frac{720*\pi }{180}

We simplify 720 as 180 goes into 720 4 times and we get

S = 4\pi

Hope this helps
