Right angled triangle calc: find a, b=24, c=33.94113

Ksenya-84 [330]

Use the Pythagorean theorem...
a²+b²=c², in this case a²=c²-b²

a²+24²=33.94113²

a²+576=1,152.00031

a²=576.000306

a=24 (If you need the exact number, not rounded, it is 24.0000064)

A cylinder has height of 7 inches and a base with a diameter of 9 inches.

bekas [8.4K]

Answer:

527.6 cubic inches

Step-by-step explanation:

The volume of a cylinder is represented by the formula $V = \pi r^{2} h$ , where r represents the radius of the base and h represents the height.

In this question, the diameter is given as 9 inches. Since the radius is half the diameter, the radius will be 4.5 inches.

Substituting in the values and solving, we get:

$V =9 \pi (4.5)^{2}\\V = 9\pi(20.25)\\V = 182.25\pi\\V = 572.6$

The Volume will be 527.6 cubic inches
