@campbell_st can you help me again?

Answer 3

angle will be 1/2 (118-48) :)

formula for angle is 1/2 *(major arc-minor arc)

Answer 5

so 1/2 *(70) =35

Answer 6

your final answer ^^

Answer 7

thankyou :) do u think u have time to help me with a few more?

Answer 8

if you can I also have this one...

Answer 9

you dont have minor arc here
so it will be half of 86
thats 43

Answer 10

isnt the answer 30?

Answer 11

3o as well
these two triangles are congruent by SSS property

Answer 12

30*

Answer 13

the answer would be 256 right?

Answer 14

no

Answer 15

major arc is 232
minor is 128
major - minor = 104
divided by 2 the answer is 52

Answer 16

remember the formula

Answer 17

oh my bad its 52

Answer 18

correct?

Answer 19

yup :)

Answer 20

for the first one I got C is that correct @aajugdar ?

Answer 21

nvm sorry I mean D

Answer 23

radius is aprox 7.95
D is correct

Answer 24

find the volume of both cylinder

Answer 25

for 2nd one

Answer 26

ratio is 1:4

Answer 27

yeah for the second one I was just finding the volume of both cylinders but I didnt know what to do after i found both volumes

Answer 28

3rd one's answer is 2833
u just hv to put value in formula

Answer 29

in 2nd
you get 12.5 first's volume
2nd's 50
so 12.5:50 = 1:4
because 12.5*4 = 50

Answer 30

oh ok ill write that down for my study guide but for the third one I dont get it

Answer 31

oh nvm I get it

Answer 32

4th one is same as 2nd one?

Answer 33

3rd well
do you know the formula for surface area of cone

Answer 34

nvm the first one sorry

Answer 35

height is 25
radius is 7.5
find the volume

Answer 36

of the oblique cone?

Answer 37

oh oh
sorry

Answer 38

oh oh ok I get the third one

Answer 39

answer will be same though
area of base is pi*r^2

Answer 40

same thing ^^
okay the last one now

Answer 41

you have to find the height here

Answer 42

aright wait a sec

Answer 43

use pythagorus

Answer 44

are you allowed to use calculator

Answer 45

in the practice test yes and in the final.. no :(

Answer 46

well you wont get these hard calculations in exam

Answer 47

so did you get height 7.8

Answer 48

now you know base and height
find the surface area

Answer 49

yeah but i used V=1/3 bh
I got 56.25 on the area of the base and then the result was 468.75...

Answer 50

o_o

Answer 51

why would u use volume formula for last one

Answer 52

google surface area of square pyramid
and use that formula
base = 3
height is 7.8

Answer 53

no for the one before it

Answer 54

area of base will be 176.71 -.-
pi*r^2
where r=7.5

Answer 55

the oblique cone

Answer 56

yeah but its base is a circle

Answer 57

so circle's area is?

Answer 58

A= pi r^2

Answer 59

yes
and r =7.5
so area of base will be?

Answer 60

well solve them
i hope you understood how to find volume and surface area for last two
u also hv height for last one now
m bit busy now
will check ur answers later

Answer 61

yes thankyou sooo much for your help im sorry I asked too many but bye and have a good night!

Answer 62

you are welcome ^^
