Awok frying pan is shaped like a spherical bowl with handles. a bit of experimentation at home persuades a cook that a wok holds about 3 l if it is 9 cm deep and the sphere has a radius of 20 cm. to be sure, picture the wok as a solid of revolution, as shown in the figure, and calculate its volume with an integral. what is the real volume of the wok? (1l=1000cm^3)

if the pizza is divided equally into 2 equal halves then you would get

πr^2/2

where r is the radius of the pizza.

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet
