Answer:
23 of the coins will be quarters
Step-by-step explanation:
Alrighty
2pi radians in a circle
so
find the circumfernce
5/2pi=60/circumfnernce
solve for circumfernece
multiply both sides by 2pi circumference
5circumference=120pi
divide both sides by 5
circumference=24pi
c=2pir
24pi=2pir
divide both sides by 2pi
12=r
the radius is 12cm
Answer:
-1 and 1
Step-by-step explanation:
(300x6)+(70x6)+(8x6)
1800+420+48
1800+468
2268
Answer: 14.967
Step-by-step explanation:
Use Pythagorean Theorem to find the missing length.
a² + b² = c²
x² + 10² = 18²
x² + 100 = 324 [Subtract 100 from both side]
x²= 224
√x² = √224 [solve the square root from both sides]
x ≈ 14.967
