Answer:
A = 140
Step-by-step explanation:
Area of a triangle:
A = 1/2bh
Given:
b = 20
h = 14
Work:
A = 1/2bh
A = 1/2(20)(14)
A = 10(14)
A = 140
Answer:
52
Step-by-step explanation:
Divide 312 by 6 to find the number of events he swam per year
Diameter be d
Radius be r
- πr²=6767
- r²=6767/π
- r²=2155
- r=46.4cm
Diameter=2r=46.4(2)=92.8cm
Answer: 4x+5
Step-by-step explanation:
Answer:
2664.3
Step-by-step explanation:
The volume of a sphere is
V = 4/3 πr³
Multiply the radius (which is the diameter divided by 2), 8.6 by itself 3 times, and them multiply it by pi and 4/3 to achieve a volume of 2664.31 or aproximatley 2664.3.
