A cone has a slant height of 25 inches and a radius of 7 cm what is the volume of the cone. Please show explanation, I have been out of school for 30 years and trying to help my son understand this.

3258.77cm3

Step-by-step explanation:

Volume of a cone = 1/3 x Pi x radius ^2 x height

Radius was given as 7cm

Height was given as 25 inches (so 63.5cm) since volume is cm^3

And PI is 22/7 or 3.142

So by evaluation, Volume = 1/3 x 3.142 x (7)^2 x 63.5

Hence volume = 3258.77cm^3

answer: yes, he is correct

step-by-step explanation: 10x-1=59

                                              1-1=0     59+1=60

60/10=x=6

3.4 pizzas

step-by-step explanation:

given is a scatter plot showing number of pizzas sold during weeks for different issues of coupon

y represents number of pizzas sold and x number of coupons issued

y is marked verticaly and x horizontally

the trend line is given as

y =3.4x+43

this says that even when no coupon is issued pizzas sold will be 43

and rate of change of pizza sold for 1 unit of coupon = slope = 3.4

i.e. when x increases by 1 unit y increases by 3.4 units

hence for each additional coupon issued 3.4 pizzas more will be sold
