Convert meters into cm. 90m=900cm, then multiply that by 712 since 1cm=712m. 900*712=640,800m. hope this helps :)
Answer:
Area of the circle = 706.5 cm²
Step-by-step explanation:
Diameter = 30cm
Radius = 15cm
Area of the circle=πr²= 3.14(15)²= 3.14×225 = 706.5 cm²
Answer: r= 1.22
Step-by-step explanation:
Formula for amount with simple interest = 
, where
P= principal value , r= rate of interest , t = time.
Given: P= $2000, t= 5 years, r= 1.25% = 0.0125

Formula to compute compound amount : 

When both have same worth then

taking log on both sides , we get

Hence, Value of r= 1.22

Answer:
The number is 1.
Step-by-step explanation:
If you simplify the equation, it goes to 4x+5=3x+6. Subtract 5 from both sides and you get 4x= 3x+1. The only number that satisfies that equation is 1.
