What percent of 33 is 96

Nataly_w [17]

96/x=100/33
(96/x)*x=(100/33)*x - we multiply both sides of the equation by x
96=3.0303030303*x - we divide both sides of the equation by (3.0303030303) to get x
96/3.0303030303=x
31.68=x
x=31.68

now we have:
33% of 96=31.68

A pile of sand has been stored in the shape of a cone. Mr. Terwilliker knows that the pile is 20 feet tall and 102 feet in circu

xenn [34]

Answer:

The area of tarpaulin is 1315.63 ft^2.

Step-by-step explanation:

height, h = 20 feet

circumference, C = 102 feet

Let the radius is r.

Circumference, C = 2 x 3.14 x r = 102

r = 16.24 feet

Let the slant height is L.

$L = \sqrt{h^2 + r^2}\\\\L = \sqrt{20^2 + 16.24^2}\\\\L = 25.8 ft$

The curved surface area is

S = 3.14 x r x L

S = 3.14 x 16.24 x 25.8 = 1315.63 ft^2
