Answer:

Step-by-step explanation:
we know that
The equation of a circle in standard form is equal to

In this problem we have


substitute


$55. Multiply 15 by 20 to find out exactly how much he needs for 20 weeks, which is $300. subtract 245 from 300 to find out how much more money he needs to add to his account.
Multiply the decimal by 100. Then add the % sign.
Answer:
C = 28.26 cm
Step-by-step explanation:
The figure shows a circle of diameter 9 inches.
The person has taken radius r as 9 inches which is wrong.
The radius must be (9/2) = 4.5 inches, such that,
Circumference = 2πr
= 2×3.14×4.5
= 28.26 cm
Hence, this is the required solution.
Answer:
cos Q = 28/53
Step-by-step explanation:
cosine = CAH
= Adjacent / Hypotenuse
adjacent length 25 and hypotenuse is 53
