If 40% reps 98
100% will rep (98/50)*100 = 245
Answer:

Step-by-step explanation:
step 1
Find the area of the circle
The area of the circle is

we have
----> the radius is half the diameter
substitute


step 2
Find the area of a sector
Remember that
The area of the circle subtends a central angle of 360 degrees
so
using proportion
Find out the area of a sector with a central angle of 108 degrees

assume

substitute

Answer:
22=-7
Step-by-step explanation:
V =

where r is radius and h is height
so when radius is (x+8) and height is (2x+3),
volume =
