A pizza is divided into 8 equal parts. what is the area of one slice if its radius is 6 inches?

Hello and Welcome to FixYa!
Area of pizza (Combined Bread + Crust) = Area=pie * (radius)^2. If divided in 8 equal parts, Area of 1 piece=Area/8.
Area= 3.1415* (0.1524)^2 Area of 1 slice= Area/8 Concerned.

If you know about area formulas of class 8 and 9,please solve my question?there is a the between of the circle,there is a rectangle of dimension 4cm and 3cm.if the rectangle will cut out what...

The diameter of the circle is the diagonal of the rectangle use Pythagoras this rectangle is a made from two 3,4,5 triangles, so the diameter is 5cm, the radius will be 2.5cm don't forget the BODMAS ordering rule (Brackets of Division Multiplication Addition and Subtraction) Also rounding to 2 decimal places. This solution is based on all four corners of the rectangle touching the circumference of the circle.

Area of a circle is P (22/7) i x Radius (squared ^2) ====> 22/7 x 2.5cm ^ 2 ====> 22/7 x 6.25cm

TOTAL AREA of CIRCLE = 19.64 cm^2

Area of the rectangle is length x width ====> 4 cm x 3 cm


The remaining portion is the circle area minus the rectangle 19.64-12 = 7.64 cm^2

If a lead pipe 1/4in.thick has an inner diameter of 1/2in.,find the number of cubic inches of lead in a pipe 10ft.long

A pipe can be seen as two cylinders, one of "air" sitting inside the other, in this case lead.
To get the volume of a pipe you thus subtract the volume of the "air" cylinder from that of the lead cylinder.
Volume of a cylinder = area of circular cross section (or pi times square of the radius) times the height (or length) => ? * r2 * h
Volume of a pipe = Volume of cylinder 1 (outer diameter) - volume of cylinder 2 (inner diameter).

In this case; Volume of outer cylinder => inner diameter 1/2" (0.5") + pipe thickness 1/4" (0.25") = 3/4" (0.75") divided by 2 to get radius = 0.375".
3.14 (?) * 0.375 * 0.375 * 120(10 feet) = 53.01438 in3

Volume of inner cylinder => inner diameter 1/2" (0.5") divided by 2 to get radius = 0.25".
3.14 (?) * 0.25 * 0.25 * 120(10 feet) = 23.56194 in3

Volume of lead in this pipe = 53.01438 - 23.56194 = 29.45244 in3

Hope this helps ;)

It wants a puk number for 07521175778

Your going to have to contact the Manufacturer or Service provider for the device. PUK numbers are unique to the devices and generated from a Math formula that depends on the device ID and as well as that number you provided. Only someone who knows the programming in your device would be able to provide such a code.

This is caused by setting the encryption to WPA-RADIUS instead of WPA-PSK on the client radio. Both the router and the client are
