The main formula of a spherical surface area is SA= 4 x Pi x r²
the circumference is C= 19cm =2 Pi r, so r = C/ 2Pi = 19 / 6.28 =3.02cm
so the surface area can be found by computing
SA= 4x 3.14x 3.02² =114.5, the nearest square centimeter is <span>A) 114 cm^2</span>
It is D that makes scene
<span />
Is this homework or classwork?
To find the total cost of Mikayla's purchase, we add together the costs of the skirts and tops. The costs of the skirts can be found be multiplying the quantity bought by the cost per skirt. Same goes for the tops.
5x + 3(9)
Simplified:
5x + 27
Step-by-step explanation:
=== [ -3(x-10)/4] + 2 = 11
==> [( -3x + 30 + 8)/4 = 11
==> -3x = 44 - 38
==> -3x = 6
==> -x = 6/3
==> x = -2
