Answer:
15 cm
Step-by-step explanation:
The formula for the surface area of the cone is ...
A = πr² +πrL = πr(r +L)
The radius of this cone is half its diameter so is (12 cm)/2 = 6 cm. Then the slant height L can be found from ...
126π cm² = π(6 cm)(6 cm +L)
21 cm = 6 cm +L . . . . . . . . . . . . . . divide by 6π cm
15 cm = L . . . . . . . . . . . . . . . . subtract 6 cm
The slant height is 15 centimeters.
Answer:45
Step-by-step explanation:
Sin^-1= 5÷7
Answer:
y+6
Step-by-step explanation:
If we increase x then we need to do it with y by the same number.
We can not increase with different numbers.
Our rule of translation now is (x+6,y+6)
(x,y)=(x+6,y+6)
We have A(-6,2) then A'(0,8)
B(-5,5) then B'(1,11)
Answer:
3. 3:5
4. 4:1
Step-by-step explanation:
Just ratios I believe, myb if it's wrong but that should be it.
Since 3 & 5 aren't divisible by anything the scale factor is just 3:5.
Since 24 & 6 are divisible by a common number, being 6, you'd divide 24:6 & get a scale factor of 4:1.
Do Circumfrence over diameter then add pi? I think
