The area for a regular decagon is a bit complicated to type out, but a quick google search "decagon formula" should bring it up.
its like A= (5/2) a^2 sqrt(5+2*sqrt(5)) so yeah just google that and plug the values that they gave you in
i got 1107.97~
the perimeter is P = 10a where a is the side length. in this case it is 12. so the perimeter is 10*(12) which is 120cm.
Answer:
i=prt ?
Step-by-step explanation:
Answer:
C. 4 and 5
Step-by-step explanation:
24 / 5 = 4.8
Option A is false since 4.8 is greater than both numbers.
Option B is also false because 4.8 is greater than both numbers.
Option C is true because 4 is less than 4.8 and 5 is greater than 4.8, making 4.8 lying between those numbers.
Best of Luck!
Answer:
180cm
Step-by-step explanation:
Vol of sphere = (4/3) pi r^3 and vol of cylinder = pi r^2 h
so
(4/3) pi 15^3 = pi (5)^2 h
(4/3) * 15^3 = 25h
h = [(4/3) * 15^3 ] / 25 = 180 cm
