Answer:
We use formula, circumference=
to get r= 7.48
Step-by-step explanation:
Here is the complete question: The circumference of a pool is 47 feet. Which formula can you use to find Radius (r), if you know that C =2πr.
Given: Circumference= 47 feet.
We will use formula of circumference to find radius (r) as given.
Circumference = 
⇒
(∵ we know π=3.14)
Cross multiplying both side to get r.
⇒ r= 
∴ radius (r)= 7.48
∴ We will use circumference formula
to find Radius (r).
A. The perimeter of a right triangle is given by summing all the sides.
4x + 2 + 7x + 7 + 5x - 4
x + 3 + 2x - 5 + x + 7
b. I think you have to combine like terms of the expressions.
16x + 5
4x + 5
c.
Large triangle: 4(3) + 2 + 7(3) + 7 + 5(3) - 4 = 12+2+21+7+15-4 = 53
Small triangle: 3 + 3 + 2(3) - 5 + 3 + 7 = 3+3+6-5+3+7 = 17
Answer:
Prime number
Step-by-step explanation:
It’s 10077 because it’s hey
Based on the picture, we know that ED is equal to DB. Therefore:
2 times ED=EB
2(10)=20
EB is 20
