Answer:
w = 6
RS = 13
Step-by-step explanation:
RS + ST = RT
(2w + 1) + (w - 1) = 18
3w = 18
; w = 6
Hence the value of RS = 2(6) + 1
; RS = 13
AC = AB + BC
56 = (x + 16) + (5x + 10)
56 = 6x + 26....then rearrange the equation to form...;
56 - 26 = 6x
30 = 6x...
where...; x = 5
AB = 5 + 16 and BC = 5(5) + 10
;AB = 21 ;BC = 35
Answer:

You know the relationship between the diagonal of a rectangular prism and the sides as 
where x, y and z are the three dimensions of the prism. from your data, 
or 
. With some simple calculation you get
, or 
Answer:
22 pi ft
Step-by-step explanation:
We can use the area to find the radius
A = pi r^2
121 pi = pi r^2
Divide each side by pi
121 = r^2
Take the square root
sqrt(121) = sqrt(r^2)
11= r
Now we need to find the circumference
C = 2*pi*r
C = 2* pi *11
C = 22 pi ft
Area of the figure is 102 cm²
Step-by-step explanation:
- Step 1: Find the area of the square with side = 6 cm.
Area of the square = (side)² = 6² = 36 cm²
- Step 2: Find the area of the trapezoid.
Length of parallel side 1 = 7 cm
Length of parallel side 2 = 21 - 6 = 15 cm
Height = 6 cm
⇒ Area of the trapezoid = 1/2 × (Sum of parallel sides) × height
= 1/2 × (7 + 15) × 6
= 1/2 × 22 × 6 = 66 cm²
- Step 3: Find the area of the figure.
Area of the figure = Area of the square + Area of the trapezoid
= 36 + 66 = 102 cm²
