Answer:
r=4
Step-by-step explanation:
Area of a circle is
A = pi* r^2
We know the area and 3.14 = pi
50.24 = 3.14 * r^2
Divide each side by 3.14
50.24/3.14 =3.14 /3.14 *r^2
16 = r^2
Take the square root of each side
sqrt(16) = sqrt(r^2)
4 =r
I think the rule might be x-9
Answer:
3.Area=πr²
d=14ft
r=7 ft
22/7*7*7
area=154ft²
5.area =1/2 bh
h=13cm
area=32.5cm²
32.5=1/2*13*b
32.5=13/2b
=5.0 or 5
base=5cm
Step-by-step explanation:
3 Hours
4 People does the job in 6 hours if there are twice as many people it gets done twice as fast
Step-by-step explanation:
