Answer:
506.7 cm²
Step-by-step explanation:
The amount of cardboard needed would be the surface area of the cone,
S= pi(r)(l+r) where r is the radius and l is the slant height.
You can find l using the Pythagorean theorem. l²=r²+h² which is l²=6²+20² and you get l = √436.
Plug r and l into the equation: S = 6pi(√436 + 6) = 506.7 cm²
Let me know if you have any questions about my steps!
Answer:
(11.4 - 22.8) / (26 - 7)
-11.4 / 19 this is the rate at which it burns - the slope
h = (-11.4/19)t + b
22.8 = (-11.4/19)7 + b
22.8 = (-79.8/19) + b
22.8 = -4.2 + b
27 = b
h = (-11.4/19)t + 27
Substitute 15 for t to determine the height of the candle.
Could you maybe provide us with a better explantion or picture?
Answer:
D, 312 CM.
Step-by-step explanation:
DE/C = 60/360 = 1/6
Cross-multiplying
C = 6DE = 6 x 52 = 312 CM
