Given radius of circle = 0.8 meters

Area of circle = pi * r*r

Area =3.14 * 0.8 *0.8 = 2.0096 meter square

Cost of one square meter of glass = $4.60

cost of 2.0096 square meter of glass = 4.60*2.0096 = 9.24416

Cost of glass = $9.24416

Here given that r= 0.8

Area of circular glass = area of circle = pi r^2

= 3.14 ( 0.8)^2 = 2.009 square meter

cost of one square meter = 4.60

cost of 2.009 square meter = 4.60 * 2.009 = 9.244

Answer $ 9.244 .

An urn contains 5 red, 6 blue, and 8 green balls. If a set of 3 balls is randomly selected, what is the probability that each of
monitta

Answer:

As a fraction, the answer is exactly 86/969

In decimal form, the answer is approximately 0.08875

=====================================================

Work Shown:

The assumption is that no replacements are made for each selection.

5 red, 6 blue, 8 green

5+6+8 = 19 total

A = P(3 red) = (5/19)*(4/18)*(3/17) = 10/969

B = P(3 blue) = (6/19)*(5/18)*(4/17) = 20/969

C = P(3 green) = (8/19)*(7/18)*(6/17) = 56/969

D = P(3 all same color)

D = A+B+C

D = 10/969 + 20/969 + 56/969

D = (10+20+56)/969

D = 86/969

D = 0.08875
