Answer 1

\[A=\frac{1}{2}h(b _{1}+b _{2})\]

Answer 2

h=11.7
one base is 15.8 and the other one is 21.8

Answer 3

area of trapezoid is: (1/2)(height)(base1+base2)
so (1/2)(11.7)(15.8+21.8)=

Answer 4

D

Answer 5

B sorry

Answer 6

yes :)

Answer 7

:D

Answer 8

Find the volume of a can of soup that has a height of 16 cm and a radius of 5 cm. Use 3.14 for pi.

A. 1,256.0 cm3

B. 251.2 cm3

C. 4,019.2 cm3

D. 502.4 cm3

Answer 9

volume of cylinder= pi*radius*height

Answer 10

B

Answer 11

whoops sorry typo: pi*radius^2 *height

Answer 12

because pi*radius^2 is the area of the base
then times height to get volume

Answer 13

thanks

Answer 14

Answer 16

C

Answer 17

yes :)

Answer 18

thank yaaa :)

Answer 19

your welcome :)

Answer 20

Find the volume of the sphere to the nearest whole number. Use pi = 3.14.

Answer 21

volume of sphere = (4/3)(pi)(radius^3)

Answer 22

i got 392.5

Answer 23

(4/3)(3.14)(5^3)=
5^3= 5*5*5

Answer 24

D

Answer 25

yes :)

Answer 26

yaay :))

Answer 27

Find the surface area of the sphere to the nearest square unit

Answer 28

surface area of sphere = (4)(pi)(radius^2)

Answer 29

B 50in2

Answer 30

in the picture you are given the diameter of 2in
therefore the radius is 1in

Answer 31

so then its A 13

Answer 32

yes :)

Answer 33
