the diameter of a football is five times the diameter of a cricket ball ratio of surface area of football and cricket ball is​
LenKa [72]

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:

a = 4\pi r^2

The surface area of the football is given as:

A = 4\pi R^2

=>A = 4\pi (5r)^2\\\\A = 100\pi r^2

Therefore, the ratio of their surface areas is:

A : a

100\pi r^2 : 4\pi r^2

= 100 : 4

25 : 1

If f(x)=3x-1 and g(x)=2x2-3, fill in the blank f(2) _____ 9(3)?
jasenka [17]

Answer:

f(2)<u>          <       </u>g(3)

The correct option is;

1. <

Step-by-step explanation:

The given function parameters are;

f(x) = 3·x - 1, g(x) = 2·x² - 3

For f(x) = 3·x - 1, when x = 2, we have;

f(2) = 3·x - 1 = 3 × 2 - 1 = 5

For g(x) = 2·x² - 3, when x = 3, we have;

g(3) = 2 × 3² - 3 = 18 - 3 = 15

Therefore, we have;

f(2) = 5 < g(3) = 15

Which gives;

f(2) < g(3)
