Answer:
11/7 feet
Step-by-step explanation:
the perimeter of a circle is πr²
and a semi circle is half of a circle then the formula would be 1/2 πr²
1/2×22/7×1 (it is 1 because we have divided the diameter to get radius
so we derived at 11/7
Answer:
1) x²+4x=2700
2) 50x50
Step-by-step explanation:
Pony area = x²
line-up area=4x
x²+4x=2700
x²+4x-2700=0
(x-50)(x+54)
So x= 50 or -54. Since it can’t be a negative number, it must be 50.
CHECK:
Square = 50x50 = 2500
Line up area = 50x4 = 200
2500+200=2700 YES
Nina would have ran 5 miles because if clara ran 10 and thats twice as far as nina 10 divided by 2 is 5
Answer:
give mah a pic
Step-by-step explanation:
Algebraically that would be expressed as 2r + 11
The product of 2 and r is 2r.
The sum of 2r and 11 is 2r + 11
