Answer:
25 : 1
Step-by-step explanation:
The diameter of the football is 5 times the diameter of the cricket ball. This means that the radius of the football is also 5 times the radius of the cricket ball.
Let the radius of the football be R.
Let the radius of the cricket ball be r.
This implies that:
R = 5r
Both balls are spherical.
The surface area of the cricket ball is given as:

The surface area of the football is given as:


Therefore, the ratio of their surface areas is:
A : a

= 100 : 4
25 : 1

0---------------
Step-by-step explanation:
Answer:
x = -4 and -2x - 8
Step-by-step explanation:
<u>Step 1: Distribute</u>
-1/3(6x + 15) - 3
-6/3x - 15/3 - 3
-2x - 5 - 3
-2x - 8
<u>Step 2: IF NEEDED SOLVE FOR X</u>
-2x - 8 + 8 = 0 + 8
-2x / -2 = 8 / -2
x = -4
Answer: x = -4 and -2x - 8
4 * √ 64 = 32 inches
----------------
find the side with the inverse formula of the Area ( if A = l², l = √A), then multiply by 4, you find the perimeter and your answer
