Answer:
A = 213.52
Step-by-step explanation:
A = 4 pi radius square
diameter = 34
radius is half of diameter
radius = 17
A = 4(pi or 3.14)(17)
A= 213. 628300444 with pi
A = 213.52 with 3.14
hopefully this helps you understand this concept
Answer:
t=10 s
Step-by-step explanation:
v=u+gt
108=10+9.8t
108-10=9.8t
9.8t=98
1. 8x=24 x=3
2 6x - 12 =12. x= 4
3. -4x+30=-14 x=11
Hope these helps!! I checked the answers and they were all right so dot worry :)
Answer:
d. 11.3 cm
Step-by-step explanation:
The radius of the circle is the length CP, which can be found using the Pythagorean theorem. Since CQ ⊥ PR, you know that Q is the midpoint of PR and PQ = 8 cm.
Then the Pythagorean theorem tells you ...
CP² = CQ² +PQ² = (8 cm)² + (8 cm)² = 128 cm²
CP = √128 cm = 8√2 cm
CP = 11.3 cm
