Answer:
Step-by-step explanation:
find the area of every face and the base
area of face 1= 2
area of face 2= 2
area of face 3 = 2
area of base 1= 1.7
7.7 in squared
area of a triangle is the base x height divided by 2
face 1- 2 x 2=4
4/2=2
2x3(theres 3 faces to a triangle) =6
area of base- 2 x 1.7= 3.4
3.2/2=1.7
add the faces and the base together
7.7
If the exact length is s, you have
.. s = r*θ . . . . θ = π/2
.. r = s/θ
.. r = 2s/π
Fill in the exact length for "s" in the formula and compute to find the radius.

Constant of proportionality is 4
equation: x/y = 4
explanation:
let's take 20 and 5 for example, if you divide 20 by 5, you will 4 of course. that's the proportionality for the first one. if you continue to divide x value by y value you will get 4. for the last two you would divide 28 by 4 and multiply 8 by 4.
