Suppose a coffee cup has a diameter of 8 cm and a height of 9 cm. what is the volume of the cup? (to nearest whole number)
a) 81 cm
b) 226 cm
c) 452 cm
d) 1018 cm

C) 452 cm

Step-by-step explanation:

plz mark as brainliest

volume = pi times radius squared times height

volume=pi times 16(4^2)times 9

volume = 452.39

true

explanation:

3/4 ÷ 3/4

step-by-step explanation:

basically divide any proper fraction with itself to fit the criteria.

so if we are using 3/4, then:

3/4 ÷ 3/4 = 1

so 1 is the quotient.

and the numerators for both these fractions is 3.   and if we divide the numerators:

3 ÷ 3 = 1

we see that quotient is equal to our original quotient as well.
