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:
40
Step-by-step explanation:
65% of 80...turn percent to decimal..." of " means multiply
0.65(80) = 52...so he completed 52 first serves
Answer:
y = 4/7x + 13/7
Step-by-step explanation:
m = 3+1/2+5 = 4/7
i used the coords (-5, -1)
y + 1 = 4/7 (x+5)
y + 1 = 4/7x + 20/7
y = 4/7x + 20/7 - 1
y = 4/7x + 13/7
They use percents in data. It is to show how many out of 100.
