A beachball has a surface area of about 615.75 square meters. Find the

Genrish500 [490]

Answer: The radius of the ball is 7 meters.

Step-by-step explanation:

Hi, to answer this question we have to apply the next formula:

Surface area of a sphere: 4 π r^2

Replacing with the value given:

615.75 = 4 π r^2

Solving for r (radius):

615.75 /4π= r^2

√(615.75 /4π) =r

r = 6.99 = 7m (rounded)

The radius of the ball is 7 meters.

Arbara signed up for dance lessons at Dance Unlimited. She was charged $55 per month for lessons and a one-time recital fee of $

kramer

Given:

Per month fee = $55

One-time recital fee = $165

The equation represents the $495 total cost that Barbara paid to Dance Unlimited.

$495=165+55m$

To find:

We need to find the number of month Barbara receive dance lessons from Dance Unlimited.

Solution:

We have,

$495=165+55m$

Here, m is number of months. We need to isolate m.

Subtract 165 from both sides.

$495-165=55m$

$330=55m$

Divide both sides by 55.

$\dfrac{330}{55}=m$

$6=m$

The value of m is 6. So, the required number of month Barbara receive dance lessons from Dance Unlimited is 6.
