step 4
Find the perimeter

Answer:
x=20
Step-by-step explanation:
3x - 10 + 5x + 30 = 180
8x + 20 = 180
8x = 160
x = 160/8
x = 20
check:
3(20) - 10 + 5(20) + 30 = 180
60 - 10 + 100 + 30 = 180
50 + 100 + 30 = 180
150 + 30 = 180
180 = 180 ✓
Answer with Step-by-step explanation:
We are given that
a.



b.Radius=2.58 cm
Substitute the values in the formula and 

Hence, the area of circle =20.9 square cm
c.Area of circle=1530 square cm

Hence, the radius of circle=22.07 cm
c.Area of circle of radius 15.2 cm=
Area of circle of radius 15.1 cm=

Hence, the area of circle whose radius is 15.2 cm is greater than the area of circle of radius 15.1 cm by 9.52 square cm .
