For A. You didn't gave the picture of the problem but I will attach it later with the picture of B. We are looking for the perimeter, the answer is <span>2 + 12 + 2 + 3 + 5 + 3 + 2 + 9 + 7 + 3 = 48 cm.
For B. The radius is 4 in. So the formula is given, 2pi r = 2(pi)(4 in) = 25.1327412 in is the circumference of a circle which only signifies three fourths.</span>
Answer:
Step-by-step explanation:
a-b=21
5a-2b=18
Using elimination, we have
5a-5b=105
5a-2b=18
So:
3b=-87 so b=-29
Substituting, a=-8
(a,b)=(-8,-29)
Answer:
Given:
endpoints at (-1, 6) and (9, -8)
Solve for:
the standard equation of a circle having endpoints of a diameter at (-1, 6) and (9,-8).

Answer:
x ≈ 0.693
Step-by-step explanation:
Using the rule of logarithms
log ⇔ n log x and lne = 1
Given
2 = 4 ( divide both sides by 2 )
= 2 ( take the ln of both sides )
ln = ln2, that is
x lne = ln2, thus
x = ln2 ≈ 0.693 ( to 3 dec. places )
Answer:
As we know if a solid object turn into another or if a thing which take a shape of one object turn into another object then there volume will be equal.
Take pie = ¶
volume of cylinder = volume of cone
¶×rsquare×h= 1/3¶r square h
18×18×32×3/24=r square
18×18×8×3/6= r square
18×18×4×3/3=r square
√18×18×2×2=r
18×2=r
r =36 cm
h= 24 cm
slant height = √36×36+24×24
slant height = √1872
slant height=
√2×2×2×2×13×3×3
slant height = 12√13 cm
