Radius is half the circumference
c= 2(square root) pieA
Answer:
Area = 702.9 or 703
Step-by-step explanation:
By Pythagoras the. first, we need to find the base!
(H)2 = (P)2 + (B)2
(82)2 = (18)2 + b2
6724 = 324 + b2
b2 = 6724-324
b2 = 6100
b = √6100
b = 78.1
note - they all are in square
Now, area of the triangle:-
1/2 * b * h
1/2 * 78.1 * 18
= 702.9
Hope it helps!
Let Joes average = x
Phil’s average is 0.250 and is 5/6X ( 5/6 of Joe’s)
5/6x = 0.250
Solve for x by dividing both sides by 5/6. When dividing by a fraction, flip the fraction over and multiply;
X = 0.250 x 6/5 = (0.250 x 6)/5 = 1.5/5 = 0.30
Joes average is 0.3
A)
distance covered
5*2/3 = 3.333
time taken = 21min
this means it takes
5*<span>6.306 = 31.53 to covers 5 km
b) </span><span>21min/3.33 = 6.306 time taken to ran 1 km</span>
