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

Answer:

The length of the portion BC of the cloth is 4.56 inches long.

Step-by-step explanation:

I suggest drawing the triangle out! It'll make it a lot easier to solve!

    A

      |35\    8 inches

      |       \

  B |90   _\ C

     x inches

Here you can use SOH CAH TOA

SOH = Sin theta =  Opposite/Hypotenuse

CAH = Cos theta =  Adjacent/Hypotenuse

TOA = Tan theta =  Opposite/Adjacent

We are going to use Sin because we have the hypotenuse and we're solving for opposite.

Sin theta (angle) = Opposite/Hypotenuse

Sin (35) = x/8

Sin (35) = 0.57 (Use a calculator)

0.57 = x/8  Now we're going to solve for x (segment BC)

0.57*8 = x

4.56 = x

The length of the portion BC of the cloth is 4.56 inches long.
