Area of canvas = total area of the cone = π r ( r + s )
r ⇒⇒⇒ radius
s = slant height
the base has 20 feet across  ⇒⇒ diameter = 2 r = 20
r = 20/2 = 10    and    s = 14

area = 10 * 3.14 ( 10 + 14 ) = 753.6 ≈ 754

The correct answer is the third

The answer is 754 ft^2
Solution:Given:Area of canvas = total area of the cone = π r ( r + s )r =radius s = slant height the base = 20 feet across  diameter = 2 r = 20r = 20/2 = 10    and    s = 14Area = 10 * 3.14 ( 10 + 14 ) = 753.6 ≈ 754
