The nine
Or is it asking for the number it was before it was rounded from the hundreths?
1. sqrt5 + 6sqrt5 = (1+6)sqrt5 = 7sqrt5 (answer is D)
2. 4sqrt2 - 7sqrt2 = (4-7)sqrt5 = -3sqrt2 (answer is B)
3. 3sqrt7 - sqrt63 = 3sqrt7 - sqrt7 * sqrt9 = 3sqrt7 - 3sqrt7 = 0 (answer is D)
4. -6sqrt10 + 5sqrt90 = -6sqrt10 + 5*(sqrt10 * sqrt9) = -6sqrt10 + 5*(3sqrt10)
= -6sqrt10 + 15sqrt10 = 9sqrt10 (answer is A)
5. sqrt6*(sqrt 2 + sqrt 3) = sqrt12 + sqrt18 = 2sqrt3 + 3sqrt2 (answer is D)
Answer:
the answer is 124.52
Cut it into 3 shapes, the bottom half circle, the top rectangle, and the middle rectangle
top rectangle:
A= bh
A= 4x10
A=40
middle rectangle:
A=bh
A=4x7
A= 28
Half circle:
A= πxr^2
A=πx6x6
A=πx36
A=56.52
Add it all up and you get the answer above
Plz review and thank :)
