Step-by-step explanation:
you know the formulas ?
the area of a circle is : pi×r²
the circumference of a circle is : 2×pi×r
with r being the radius, which is half of the diameter.
so, here, r = 10/2 = 5 m
area = pi×r² = pi×5² = pi×25 or 25×pi m²
circumference = 2×pi×r = 2×pi×5 = 10×pi m
for the approximation we make the calculations with pi on the calculator and round to the nearest hundredth.
area = 25×pi ≈ 78.54 m²
circumference = 10×pi ≈ 31.42 m
B. 4.5=2m+g
f. 9.25=3m+2g
1.25=m
sub
b. 4.5=2(1.25)+g
f. 9.25=3(1.25)+2g
b. 4.5=2.5+g
f. 9.25=3.75+2g
minus 2.5 from both sides on the b. equaion and minus 3.75 from both sides on the f. equation
b. 2=g
f. 5.5=2g
divide both sides of f. equation by 2
b. 2=g
f. 2.75=g
2.75-2=0.75

5+2=7, so the first blank is 2.
For the second blank, you just need two numbers in the box that when added, equals 7. (So 1,6 or 3,4)
