Answer: 87/13
Step-by-step explanation: You take you 5 and times it by 13 and + 9 because the equation is saying 13/13 5 times plus the 9/13,
So 6*13 = 78 78+9=87 and then you take the 87 and put it over the 13,
So, now you have your answer: 87/13
Answer:
1/49
Step-by-step explanation:
You wrote the problem correctly. You just needed to multiply instead of add.
1/7*1/7=1/49
So the answer is 1/49.
We know that
area of the circle=pi*r²
circumference==2*pi*r----------> r=circumference/(2*pi)
circumference=25 1/7 in----> (25*7+1)/7----> 176/7 in
r=(176/7)/(2*22/7)----> r=176/44----> r=4 in
area of the circle is equal to the area of the cake
area=pi*r²---> (22/7)*4²-----> area=50.29 in²
the answer is
50.29 in²
