43
48 - 27(since they left) + 22(since they joined) = 43
Answer:the answer is 4 to the square root of 2
Step-by-step explanation:
From the information we have the diameter of the circle is 10 cm.
Area of a circle is given by 1/4π d²
A = 1/4 π d²
π = 3.14
d² = 10² = 100
So we now calculate.
A = 1/4 × 3.14 × 100
A = 0.25 × 3.14 ×100
A = 78.5 cm²
Using radius :
The radius of this circle is 10 ÷ 2 = 5
A = π r²
A = 3.14 × 5²
A = 3.14 ×25
A = 78.5 cm²
So we still get the same answer.
Answer:
224 pounds
step by step :
one person eat 56 pound and we have four person so we must say that :
56 × 4 = 224 pounds
I got -512 because the pattern is adding -9.
I hope this helps! :D
