Question

Titans crime is at foot!

Find the diameter of a cone that has a volume of 83.74 cubic inches and a height of 5 inches. Use 3.14 for pi.
3 inches
4 inches
8 inches
16 inches

Answer 1

lets fight this question and get some pizza!

Answer 2

Let the radius be r... Then V=(1/3) *3.14*r^2*h
now put the values of V and h

Answer 3

r means ratio?

Answer 4

so r^2=3V/(3.14*h)=3*83.74/(3.14*5)=16.001 so r =4 i.e. d=2r=8

Answer 5

r is radius and d is diameter

Answer 6

8inches is the answer

Answer 7

Thank you, we shall celebrate with pizza! At the tower!

Answer 8

@jango_IN_DTOWN Can you show me how to do this? Find the area of a circle with a diameter of 12 inches. Use 3.14 for pi.
37.68 in2
113.04 in2
339.12 in2
452.16 in2

Answer 9

First tell the the formula of the area of a circle

Answer 10

uh

Answer 11

A = π × r2?

Answer 12

NOWAIT tt

Answer 13

correct

Answer 14

if r is the radius then area= pi * r^2 for a circle

Answer 15

now diameter=2*radius

Answer 16

so r=d/2 here d=12, so r=6

Answer 17

area= pi * 6^2=3.14*36=113.04

Answer 18

So you're suppose to divide the numbers by pie?

Answer 19

diameter is given.. to get the radius, divide the diameter by 2

Answer 20

then area =pi*r^2 here pi=3.14 and r=6

Answer 21

Ah okay thank you
