Question

A conical tent made of canvas has a base that is 20 feet across and a slant height of 14 feet. To the nearest whole unit, what is the area of the canvas, including the floor? Use 3.14 for p. A. 754 ft2 B. 1,193 ft2 C. 2,135 ft2 D. 534 ft2

Answer 1

in other words, the question is asking for the entire surface are:
\[SA = Pi(rs) + Pi(r ^{2})\]
where s is the slant height and r the radius, substitute and simplify

Answer 2

Answer 3

\[Surface \space area \space of \space a \space cone = \pi *r*(Slant \space height) + \pi * r^2\]

Answer 4

r is 1/2 of the diameter

Answer 5

which would be 1/2 of 20

Answer 6

so r = 10

Answer 7

@eyust707 continue

Answer 8

so just plug in the numbers to the equation i posted
