Answer: the answer is D
Step-by-step explanation:
Use Pythagorean theorem.
a^2 + b^2 = c^2
D.
21^2 + 72^2 = 75^2
441 + 5184 = 5625
Step-by-step explanation:
Diameter (d) = 22 inch
Radius (r) = d/2= 22/2 = 11 inch
π = 3.14
Now
Circumference = 2πr
= 2* 3.14 * 11
=69.08 ich
And now
Area = πr²
= 3.14 * 11²
= 379.94 inch²
Hey there,
It take 45 min to complete 75% of the wall
1% = 45 / 75
= 0.6
100 % = 0.6 x 100
= 60 min
It takes her 60 mins or 1 hour to finish building the wall.
Hope this helps :))
