Answer:
1,017.36 ft²
Step-by-step explanation:
surface area of the cone = π×r×s
= 3.14 × 13.5 × 24
= 3.14 × 324
= 1,017.36 ft²
2/5 of 100 would be 40%
1/9 an hour would be 1/9 x 40 % = 4.44% every hour
Total hours left would be 40% / 4.44%= 9.0009 = 9 hours
Answer:
(64x -11)/y
Step-by-step explanation:
Multiply 4x into the parenthesis.
60x + 4xy -11y
Divide by y.
(60x + 4x -11)/y
(64x -11)/y
Its k^17

Answer:
a. 40 ft²
b. 21 ft²
c. 61 ft²
Step-by-step explanation:
Rectangle area formula: l * w
Triangle area formula: 1/2(bh)
10 * 4
40 ft² for the rectangle
1/2(7 * 6)
1/2(42)
21 ft² for the triangle
40 + 21
61 ft² in total (both the rectangle & the triangle)
