The pizza is round and has a radius of 8 inches. Tina only ate 1/3 of the pizza and took home the rest of it. How many square inches of the pizza did Tina eat?

Step-by-step explanation:

GIVEN: The pizza is round and has a radius of . Tina only ate of the pizza and took home the rest of it.

TO FIND: How many square inches of the pizza did Tina eat.

SOLUTION:

radius of pizza

Area of circular pizza

putting values we get,

Area of pizza

Now, Tina only ate of her pizza

Area of pizza ate by tina

Hence tina only ate of pizza

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.
