We know that
[length of a circumference]=2*pi*r
diameter=90 cm-------------> r=d/2--------> r=45 cm
[length of a circumference]=2*pi*45----------> 90*pi cm
<span>with 1 revolution will go the length of the wheel</span>
if 1 revolution is-------------------> 90*pi cm
5 revolution is--------------------> X
X=5*90*pi----------> 1413 cm
the answer is 1413 cm
D=11.25
You can make a proportion of the bigger triangle to the smaller triangle
8/15=6/d
cross multiply
8d=90
d=11.25<span />
Answer: Mark me brainliest..
Step-by-step explanation: and imma put the answer inside the comments if you do so. youve got nothing to lose! :D
Solve for y by simplifying both sides of the equation, then isolating the variable.
y = 7x/2 - 3
Answer:
b=5d+5f
solve for b by simplifying both sides and then isolating the variable.
