Acone has a radius of 200 m at its base. the cone is 50 m high. how much space is inside the cone?

The question "how much space is inside a solid?" is actually asking about the volume of that solid.

The volume of a cone is given by

where h is the height of the cone, and r is its radius.

So, you only need to plug in the values:

step-by-step explanation:

you have to realize that a line equals 180 degrees

answer: - (a)

(b) 88 seats

step-by-step explanation:

given: in an auditorium, there are 22 seats in the first row and 28 seats in the second row.

thus first term=

second term=

the number of seats in a row continues to increase by 6 with each additional row.

⇒d= 6

a) given formula :

substitute n=12 in the explicit rule formed in (a)

∴there are 88 seats in 12 rows.
