Find the surface area of this shapePLS HELP, AM NEEDING TO TURN THIS IN, IN LIKE AN HOUR​

Mathematics

Answer:

48.25

Step-by-step explanation:

When finding an area of a triangle it is area = base times height divided by 2.

AKA a =bh1/2

We can do that for all sides in this equation.

For the bottom we can do:

5*4.3=21.5       21.5/2 = 10.75

For one side we can do:

5*5 = 25           25/2 = 12.5

12.5 = one side, but there are three so,

12.5*3 = 37.5

37.5 + 10.75 = 48.25

Contact [7]
Answer: The length of the bottom left side is 14.

To find the length of this side, we need to know the relationship between the different sections when chords cross each other.

The relationship is that if you multiply the 2 parts of each chord together, it will equal the product of the two sides in the other chord.

Our equation can be written as:

7(8) = 4(x)
56 = 4x
14 = x

Set up, but do not evaluate, the integral that represents the length of the curve given by
netineya [11]

Answer:

L = ∫₀²ᵖⁱ √((1 − sin t)² + (1 − cos t)²) dt

Step-by-step explanation:

Arc length of a parametric curve is:

L = ∫ₐᵇ √((dx/dt)² + (dy/dt)²) dt

x = t + cos t, dx/dt = 1 − sin t

y = t − sin t, dy/dt = 1 − cos t

L = ∫₀²ᵖⁱ √((1 − sin t)² + (1 − cos t)²) dt

Or, if you wish to simplify:

L = ∫₀²ᵖⁱ √(1 − 2 sin t + sin²t + 1 − 2 cos t + cos²t) dt

L = ∫₀²ᵖⁱ √(3 − 2 sin t − 2 cos t) dt
