Answer:
17.2a+14.6
Step-by-step explanation:
Answer:
r = - 4
Step-by-step explanation:
Given
- 1.5(4 - r) = - 12 ( divide both sides by - 1.5 )
4 - r = 8 ( subtract 4 from both sides )
- r = 4 ( multiply both sides by - 1 )
r = - 4
To find the diameter of the circle it’s C=(2)(3.14)(r) radius is 8/2 which is 4 so 2(3.14)(4) is 25.13 + 36 is 61.13
The perimeter of the whole figure is 61.13in^2
