ANSWER:

1.SOLUTION

V=lwh/3

V=8cm×6cm×10cm divided by 3

V=480÷3

Volume= 160cm³ is the answer

2.SOLUTION

V=πr²h

V=3.14159 (4)² (8)

V=3.14159 (16) (8)

V=402.12in³ is the answer

3.SOLUTION

Radius of sphere =5cm

Volume of sphere=4/3πr^3

Volume =4/3×22/7×125

Volume = 523.8095cm^3 is the answer

4.SOLUTION

the formula of a volume of a cone is

5×h÷3

So, find the area of a circle base.

7×7=49

49×3.14=153.86

And multiply it by eight

153.86×12=1846.32

And divide it by 3

1846.32÷3=615.44

So the volume is 615.44 is the answer
