Step-by-step explanation:
always write what you know
circumference
U = 2 x pi x r
r = d/2
U = 39.25
rearrange and solve for r
U / (2 x pi) = r
solve for diameter
2r = d
Answer:
4) (2)(4)(3.14) = 25.12 m
5) (12)(3.14) = 37.68 ft
6) (2)(2)(3.14) = 12.56 yd

Answer:
SWEEEET!!
Step-by-step explanation:
:D
15m ^3 - 26m^2 +11m - 4 is the result of the product.
(5m^2 -2m +1)(3m-4)
On opening the bracket, we multiply the terms,
= 15m^3 -6m^2 +3m -20m^2+8m -4
= 15m ^3 - 26m^2 +11m - 4
This is the result of the product
When we mutiply the two equations.
