A = 1/2(12)(6)
A = 36

2) (pink)
A = 1/2(8+16)(14)
A = 1/2(24)(14)
A = 168

Hey there :)

1st Shape:
It is a trapezium

We know the area formula of a trapezium
Area = \frac{1}{2}(base1+base2)(height)

We know the:
Base 1 = 4 units
Base 2 = 8 units
Height = 6 units

Apply the formula:
A = \frac{1}{2}(4+8)(6) = 36 units²

2nd Shape:
It is a trapezium

We are given:
Base 1 = 8 units
Base 2 = 16 units
Height = 14 units

Apply the formula
Area = \frac{1}{2} (8+16)(14) = 168 units²

31,50 is 42% os what number
sergeinik [125]
\frac{31,50}{x}=\frac{42}{100}

The right fraction represents the percentage; 42 over 100 (100 is the total), or 0.42.
The left fraction is the part number over the whole number. The whole number is unknown, so we use 'x'.


\frac{31.50}{x} = \frac{42}{100}\\\\cross\ multiply\\\\31.50\times100=3150\\42\times x=42x\\\\3150=42x\\x=75
Your answer is 75.

What is the surface area of a sphere with radius 2?
VladimirAG [237]

\textit{surface area of a sphere}\\\\ SA=4\pi r^2~~ \begin{cases} r=radius\\[-0.5em] \hrulefill\\ r=2 \end{cases}\implies \begin{array}{llll} SA=4\pi (2)^2\implies SA=16\pi \\\\\\ SA\approx 50.27 \end{array}

Find the area of the region that lies inside the first curve and outside the second curve. r = 6 − 6 sin θ, r = 6
yan [13]
Each curve completes one loop over the interval 0\le t\le2\pi. Find the intersections of the curves within this interval.

6-6\sin\theta=6\implies 1-\sin\theta=1\implies \sin\theta=0\implies \theta=0,\theta=\pi

The region of interest has an area given by the double integral

\displaystyle\int_\pi^{2\pi}\int_6^{6-6\sin\theta}r\,\mathrm dr\,\mathrm d\theta

equivalent to the single integral

\displaystyle\frac12\int_\pi^{2\pi}\bigg((6-6\sin\theta)^2-6^2\bigg)\,\mathrm d\theta

which evaluates to 9\pi+72.
