What is the surface area of a mini basketball with a circumference.of 25 and radius of 4

1 answer:

4 0

The formula to find the surface area of a sphere is A=4(3.14)r². So if you plug in the data you would get,
A=4(3.14)4²
A=(12.56) (16)
A=200.96
You mught want to check over it so you will be able to solve it for yourself the next time you have this question.

Answer: 12

Step-by-step explanation:

a^2 times b^2 =c^2

4^2 times 3^2=c^2

16 times 9=c^2

144=c^2

$\sqrt{144}$ = $\sqrt{c^2}$

A, B & C form a triangle where

slavikrds [6]

Answer:

10.9

Step-by-step explanation:

Pythagoras theorem- a² + b² = c²

Since this is a right angle with each side on the right angle's length given you can use pythagoras theorem.

7² + 8.44² = c²

= 49 + 70.56 = c²

= 119.56 = c²

∴ c = √119.56

= 10.9
