Answer:
Step-by-step explanation:
r=13in
Perimeter of a circle is 2πr
P=2×22/7×13
P=81.71in.
If it will make 3 revolution then it will have move 3 times it perimeter
3×81.71
245.14in
The distance the wheel will traveled is 245.14in
This is the answer of your question
Answer:
7=2+r
Step-by-step explanation:
basic algebra, can u mark brainliest answer please?
<span>h= (-16t^2 + 28t + 7) </span>
find the derivative to get time<span>
<span>
h' = (-32t + 28)
When the ball reaches its maximum height, its
vertical velocity (h’) will be 0 </span></span>
<span>
<span>
0 = -32t + 28 </span></span>
-32t=-28
<span><span>-28/-32 = </span>0.875
seconds </span><span>
<span>
The ball reaches its maximum height in 0.875
seconds after being thrown; plug and chug and:
h= (-16(0.875)^2 + 28(0.875) + 7) = 19.25 feet</span></span>
Max height = 19.25 feet, time = 0.88 seconds
