Match each cones measures to its corresponding volume. Cones:
1. Radius=5 in height=4 in
2. Base area= 16pi in ²
Height= 6 in
3.diameter= 12 in height 5 in

Volumes:
1.v=100/3pi in ³
2. V=32pi in ³
3. V=60pi in ³

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.

i belive those are the ones that are under 90 degreese.

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9

1. 3. can also be expressed as (22/7)

2. -4.5

3. 3.6
