Hello? pooja195?

Answer 3

LA = ½ps

where p is the perimeter of base.
and s is the Slant height.

Answer 4

Perimeter = 15 + 15 + 15 + 15 = 60

LA = ½(60)(16)

Answer 5

Option D

Answer 6

Answer 14

well 3.14

Answer 15

alright hol on

Answer 16

okay

Answer 17

Generally, finding volume involves multiplying 3 dimensions together. You're doubling all these dimensions. So, instead of a*b*c you get (2a)*(2b)*(2c).

Answer 18

alright so now what

Answer 19

so the answer is 6

Answer 20

so yr answer would be corrrrrect

Answer 21

oh hah i jsut made a mistake yes thank you

Answer 22

A cone has a base area of 3 in² and a lateral area which is 1.5 times bigger than the base area. The surface area of the cone is _____ in².

4.5

6.0

7.5

9.0

Answer 23

how bout this one

Answer 24

is 4.5 correct i just timed them

Answer 25

Lateral area = 1.5 (3) = 4.5

Surface area = lateral area + base area
= 4.5 + PI r^2
= 4.5 + 3 = 4.5+3 = 7.5

Answer 26

@pooja195

Answer 27

ah okay

Answer 28

What is the lateral area of a cylinder with a radius of 10 in and a height of 6 in? Use 3.14 for

if u post the question together it would help :-)

Answer 32

just a thought

Answer 33

oh sorry. well i jsur seperated the answers from the question

Answer 34

so what did u get

Answer 35

By 'lateral area' I assume you mean the curved area.
Lateral area = height * circumference
= 6 in * 2 * 3.14 * 10 in
= 376.8 in^2

Answer 36

Thank you ..

Answer 37
