do you want us to add, subtract, multiply, divide...what..?
Answer:
31.42
Step-by-step explanation:
radius= half diameter
circumfrence= 2pi*r
A^2 + b^2 = c^2
a^2 + 15^2 = 17^2
a^2 + 225 = 289
a^2 = 289 - 225
a^2 = 64
a = sqrt 64
a = 8 cm
The answer is in the question. The question says he used 2/3 of it to make sandwiches. Unless your asking what 2/3 of 7/8 is then the answer would be 7/12.
you just multiply the top numbers together and the bottom numbers together and then reduce.
