Find the volume of this square pyramid to the nearest tenth.

1 answer:

7 0

Formula:

V = 1/3 * b^2 * h

Plug in what we know:

V = 1/3 * 7^2 * 16

Simplify the exponent:

V = 1/3 * 49 * 16

Multiply all 3 numbers together:

V = 261.3cm^3

What is the length of arc S? (The angle in the figure is a central angle in radians)

IgorC [24]

Answer:

π/90 or 0.0035 units

Step-by-step explanation:

equation: length of the arc = ∠of the angle/360 * circumference

Substitute: S = 0.4/360 * 10π --> C = 2πr

Simplify: S = 1/900 * 10π

Simplify: S = π/90 ≈ 0.003489 units

Write in lowest terms: 7x2 - 13x - 2 27x2 - 6x - 1

Ksju [112]

So... get the like-terms and add/subtract $7x^2-13x-2+27x^2-6x-1
\\ \quad \\
\textit{add/subtract the like-terms}
\\ \quad \\
\boxed{7x^2+27x^2}\quad \boxed{-13x-6x}\quad \boxed{-1-2}$

see what that gives you
