Find the area of the triange below<br><br>units given are cm, cm^2, cm^3

notsponge [240]

Answer:

$A=150\ cm^2$

Step-by-step explanation:

The Hypotenuse of triangle, H = 25 cm

Base = 15 cm

Height = 20 cm

We need to find the area of the triangle. The area of a right-angled triangle is given by :

$A=\dfrac{1}{2}\times b\times h\\\\A=\dfrac{1}{2}\times 15\times 20\\A=150\ cm^2$

So, the area of the triangle is equal to $150\ cm^2$ .

The volume V (in cubic feet) of a right cylinder with a height of 3 feet and radius r (in feet) is given by V=3πr2. Solve the fo

Kitty [74]

Answer:

$r=\sqrt{\frac{V}{3\pi}}\\\\r\approx 5.00\ ft$

Step-by-step explanation:

-The volume of a cylinder is given by the formula:

$V=3\pi r^2$

#We make r the subject of the formula:

$V=3\pi r^2\\\\r^2=\frac{V}{3\pi}\\\\r=\sqrt{\frac{V}{3\pi}}$

#We then substitute for the stated volume and solve for r:

$r=\sqrt{\frac{V}{3\pi}}, V=236\\\\\therefore r=r=\sqrt{\frac{236}{3\pi}}\\\\r=5.00404\approx\ 5.00\ ft$

Hence, the cylinder's radius is approximately 5.00 ft
