Mercury the liquid metal? 674.1°F or 356.7°C
Answer:
B.) 54π units²
Step-by-step explanation:
First, we need to find the height of the cone. We can do this using the Pythagreom Theorem.
a² + b² = c² <----- Pythagreom Theorem
3² + b² = 15² <----- Insert side lengths
9 + b² = 225 <----- Solve 3² and 15²
b² = 216 <----- Subtract 9 from both sides
b = 14.7 units <---- Take square root of 216
Now, we can use the surface area of a right cone equation to find the final answer.
r = 3 units
h = 14.7 units
SA = πr(r + √(h² + r²)) <----- Surface Area equation
SA = π(3)(3 + √(14.7² + 3²)) <----- Insert values
SA = π(3)(3 + √(216 + 9)) <----- Solve 14.7² and 3²
SA = π(3)(3 + √225) <----- Add 216 and 9
SA = π(3)(3 + 15) <----- Take square root of 225
SA = π(3)(18) <----- Add 3 and 15
SA = 54π units² <----- Multiply 3 and 18
Answer:
Step-by-step explanation:
The SA would be 10e² because there are 10 squares.
The V would be 2e³ because there are 2 cubes.
Part A
If e = 5 cm, simply plug it into the SA formula we have already.
SA = 10e² = 10*5² = 10*25 = 250 cm².
Part B
If e = 5cm, simply plug it into the V formula we have already.
V = 2e³ = 2*5³ = 2*125 = 250 cm³.
Now we need to find what percent of 250 is 150?
250p = 150
p = 150/250 = 3/5 = 0.6 = 60%
