Kentucky Academic Standards (KAS) for Mathematics — Kentucky

How the KSA reports it

Kentucky KSA is a state summative assessment built on Kentucky Academic Standards (KAS) rather than a separate national framework. For mathematics, the assessed content closely follows Common Core–style grade-band domains in grades 3-8 and uses Kentucky high-school conceptual categories in grade 10.

Blueprint & weighting

KSA uses the Independent / state-specific framework (by grade domains structure).

Find the surface area of a sphere with radius 11. Use π=3\pi = 3.

SA=4πr2=4×3×1=12SA = 4 \pi r^{2} = 4 \times 3 \times 1 = 12.

Each interior angle of rectangle WXYZWXYZ measures (3x−12)°(3x-12)°. What is the value of xx?

Every interior angle of a rectangle measures 90°90°, so 3x−12=903x-12=90 and x=34x=34.

In a right triangle, cos⁡α=513\cos\alpha = \dfrac{5}{13} and tan⁡α=125\tan\alpha = \dfrac{12}{5}. What is sin⁡α\sin\alpha?

sin⁡α=tan⁡α⋅cos⁡α=125⋅513=1213\sin\alpha = \tan\alpha \cdot \cos\alpha = \dfrac{12}{5} \cdot \dfrac{5}{13} = \dfrac{12}{13}.

In a 30∘30^{\circ}-60∘60^{\circ}-90∘90^{\circ} triangle, the hypotenuse is 22.22\textsf{.} What is the short leg?

In a 30∘30^{\circ}-60∘60^{\circ}-90∘90^{\circ} triangle, the short leg is half the hypotenuse: 222=11.\dfrac{22}{2} = 11\textsf{.}

In a 45∘45^{\circ}-45∘45^{\circ}-90∘90^{\circ} triangle, a leg is 9.9\textsf{.} What is the hypotenuse?

In a 45∘45^{\circ}-45∘45^{\circ}-90∘90^{\circ} triangle, the hypotenuse is a leg times 2:\sqrt{2}\textsf{:} 92.9\sqrt{2}\textsf{.}

An ice machine makes spherical ice balls with a diameter of 66 centimeters. What is the volume of one ice ball, in cubic centimeters?

The radius is half the diameter: r=3r = 3 cm. Then V=43πr3=43π(3)3=36πV = \dfrac{4}{3}\pi r^{3} = \dfrac{4}{3}\pi (3)^{3} = 36\pi cubic centimeters.

Practice playeasy

Find the volume of a cone with radius 22 and height 99. Use π=3\pi = 3.

V=13πr2h=13×3×4×9=36V = \dfrac{1}{3}\pi r^2 h = \dfrac{1}{3} \times 3 \times 4 \times 9 = 36.

In △ABC\triangle ABC, m∠A=(x+8)°m\angle A=(x+8)°, m∠B=(2x+17)°m\angle B=(2x+17)°, and m∠C=(x+55)°m\angle C=(x+55)°. What is the value of xx?

The three interior angles sum to 180°180°: (x+8)+(2x+17)+(x+55)=180(x+8)+(2x+17)+(x+55)=180, so 4x+80=1804x+80=180 and x=25x=25.
