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
Answer:
12
Step-by-step explanation:
12 × 2 = 24 and 6 + 6 + 6 + 6 = 24
Step-by-step explanation:
Angle at Center = 2 * Angle at Circumference
Therefore B = 2A.
When B = 100°, A = 100°/2 = 50° (B),
When A = 48°, B = 2(48°) = 96°. (C)
here 8x and (2x+60) are corresponding angles
since line l1 and l2 are parallel, so the two angles will be equal
8x=2x+60
8x-2x=60
6x=60
dividing by 6
x=10
option D. 10 is correct
785.63-(57+125)
=785.63-182
=603.63
603.63+57.25=$660.87
