The approximate surface area of the balloon is 199 cm².

The approximate volume of the balloon is 262 cm³

<h3>What is the surface area and the volume of the balloon? </h3>

Radius of the balloon = circumference / 6.2832

25 / 6.2832 = 3.98cm

Surface area = 4πr²

4 x 22/7 x 3.97² = 199 cm²

Volume =  4/3πr³

4/3 x 22/7 x 3.97³ = 262.20 cm³

Write the equation for the perpendicular bisector of the given line segment.
spayn [35]

Answer:

C

Step-by-step explanation:

find the equation of the segment  two point (-5,5) and (-2,-4)

m=y2-y1/x2-x1 =5-(-4)/-5-(-2) =9/-3 = -3

find b : y= -3x+b

            5 =-3(-5) +b

            b=-10

the equation is : y=-3x-10

the perpendicular line is y=1/3 x -2/3
