BRAINLIEST !! Pls at least take a look , answer all or don't answer

1) 706.86

2) 726 cm^3

3) V= 792 km^3

4) 209.4 ft^3

Step-by-step explanation:

#4: V=πr2h

3.14 times the radius, then the height divided by 3

#3 V=lwh

V=lwh3 length times width times height divided by 3

#2 ^same as #3 steps

#1 A=πr2

pi times the radius squared

1. 706.5

2. 726

3. 396

4. 130.8

Step-by-step explanation:

1. Area = pi × r²

= 3.14 × 15²

= 706.5 ft²

2. Volume = ⅓ × base area × height

= ⅓ × 11² × 18

= 726 cm³

3. Volume = ⅓ × base area × height

= ⅓ × ½ × 9 × 12 × 22

= 396 km³

4. radius = 10/2 = 5

Volume = ⅓ × base area × height

= ⅓ × 3.14 × 5² × 5

= 130.83333 ft³

the answer is b.

step-by-step explanation:

identity property is where 0+whatever number=whatever number. basically 0+ a number.

no he doesnt because "-16' is negatiive
