The radius is 5cm

Step-by-step explanation:

The surface area of a sphere is given by:

SA = 4\pi r^2

Here

Given

SA = 100π cm^2

Putting the values in the formula

100\pi = 4\pi r^2\\r^2 = \frac{100\pi}{4\pi}\\r^2 = 25

Taking square root on both sides

\sqrt{r^2} = \sqrt{25}\\r = 5 cm

The radius is 5cm

Keywords: Surface area, Radius

g100num [7]

Answer:  54 mph

Step-by-step explanation:

d-the distance

s+9  -  the speed to the conference

d=6*(s+9)

s- is the speed on the way back home

d=7*s

so    6*(s+9)=7*s

       6s+54=7s

     -6s          -6s

The perimeter of a rectangle is 15x + 17 y if the length is 7/2x + 7y then find the width of the rectangle A) 4x + 3/2y B) 8x +
tigry1 [53]
The equation for the perimeter of a rectangle:

P = 2L + 2W

We’re given P and L and asked to find W:

15x + 17y = 2(7/2x + 7y) + 2W
15x + 17y = 7x + 14y + 2W
2W = 8x + 3y
W = 4x + 3/2y

Answer is A.
