20 times 98 is the product of 20 and 98
Thus 20 times 98 = 20 × 98 = 1960
Answer:
55
Step-by-step explanation:
To find volume of a cylinder, you must find the area of the base and multiply it by the height of the object.
V=Bh where B=area of the base. Since the base is a circle, we must find area of the circle. A=pi(r^2)
A=3.14(6^2) Since it gave us the diameter, we take half for radius. Solve A=3.14(36)
A= 113.04 square cm
Now to find volume.
V=113.04•11
V=1243.44 cubic cm
Now find volume of the cone on top.
V=1/3Bh again with B= area of the base (pi)(r^2)
Since the two objects share a base, we can use the area of the cylinder as above.
V=1/3(113.04)9
We have to do a little simple math to determine the height of just the cone. Total height is 20-11 height of the cylinder. The difference is 9.
V=1/3(113.04)9 multiply
V=339.12 cubic cm
Now add the two volumes together to find total volume.
Total V=1243.44+339.12
V=1582.56 cubic cm
Answer:
Equilátero si todos sus lados son iguales o isósceles si la base es menor que sus otros dos lados.
Step-by-step explanation:
Revisar fotografía adjunta.
Comienzas dibujando la línea de 6 cm. Luego encuentras su mediatríz, la cual está a 3 centímetros de cualquier extremo de la línea.
Luego dibujas el triángulo como se muestra en el dibujo. Dependiendo de la longitud de los lados, el triángulo podría ser equilátero si todos sus lados son iguales o isósceles si solo los dos lados inclinados son iguales y la base es diferente.
Answer: (-2, -2)
Step-by-step explanation:
We will graph the equations. Then, we will decide which of the points is a solution. See attached for the graph. The point of intersection is the solution. This means the only solution is,
