Answer:
Step-by-step explanation:
Original 873 New 781
The new went down by about 10.5%
873*10.5%= 91.67
873-91.67= 781.33
It decreased 10.5%
V of cone=(1/3)(pi)(h)(r^2)
V of cylinder=(pi)(h)(r^2)
1.
r=6
h=10
v=(1/3)(pi)(10)(6^2)
v=1/3pi10(36)
v=1/3pi360
v=120pi
answer is B
2.
r=d/2
d=10
10/2=5=r
V=(3.14)(5)(5^2)
V=3.14(125)
V=392.5
answer is B
3. 9.2, 3.7
V=(pi)(9.2)(3.7^2)
V=(pi)(9.2)(13.69)
V=(pi)(125.948)
input 125.948
4. v=(1/3)(pi)(12)(3^2)
V=(1/3)(pi)(12)(9)
V=(pi)(12)(3)
V=pi(36
v=36pi
v=36(3.14)
V=113.04
input 113.04
