Question

Janine made a cylindrical vase in which the sum of the lateral area and area of one base was about 3000 square centimeters. The vase had a height of 50 centimeters. Find the radius of the vase. Explain the method you would use to find the radius.

Answer 1

this one?

Answer 2

yes :D

Answer 3

aright, let me see.

Answer 4

2(pi)r*50+(pi)r^2 = 3000

Answer 5

the left term is the lateral area: 2pi*r*h the middle term is the area of the base

Answer 6

so i solve for r?

Answer 7

2π x r x 50 = 3000 (solve for r), 100π x r = 3000, π x r = 30, r = 9.55 or 10 cm.

Answer 8

oh r is the radius duh omg

Answer 9

wait is the answer 10cm?
