Answer:
The equation that represents this problem is p - 2 = 18 ⇒ D
Step-by-step explanation:
Let us solve the question
∵ p is the time it takes Tomás to bike to the park
∵ The time it takes Tomás to bike to the community center is 2 minutes
less than half the time it takes him to bike to the city park
→ That means multiply p by , then subtract 2 from it
∴ The time to the community center = (p) - 2
∴ The time to the community center = p - 2
∵ It takes Tomás 18 minutes to bike to the community center
→ Equate The time to the community center by 18
∴ p - 2 = 18
∴ The equation that represents this problem is p - 2 = 18
It's unclear what the planes are supposed to be, so I'll take and
with
.
The cross sections are disks with diameter , so each disk of thickness
has a volume of
Then taking infinitesimally thin disks, we find the solid has a volume of
Since
and
it follows that the volume is
