Answer:
262.44 cubic metres.
Step-by-step explanation:
First, we can calculate the volume of the cylinder by doing pi * r^2 * h. In this case, r is 5 / 2 and h is 7.
pi * (5/2)^2 * 7 = pi * 25/4 * 7 = pi * 6.25 * 7 = pi * 43.75 = 3.14159265 * 43.75 = 137.4446784 cubic m.
Seconds, we calculate the volume of the cube. It is 5^3 = 5 * 5 * 5 = 25 * 5 = 125 cubic m.
137.4446784 + 125 = 262.4446784, which is about 262.44 cubic metres.
Hope this helps!
m <3 = 52 °
Explicación paso a paso:
Puntos para recordar
1). El rombo es un paralelogramo. Los ángulos opuestos son suplementarios.
2). Las diagonales bisecan los ángulos de cada esquina.
3). Los ángulos alternos internos son iguales.
4). Todos los lados son iguales
Para encontrar la medida de <3
De la figura podemos ver un paralelogramo.
Se da que, n <3 = 80
Sabemos que m <1 = m <3
Por propiedad de suma de ángulos,
m <1 + m <1 + m <3 = 180
3 * m <1 = 180 - 80 = 100
<m1 = 100/2 = 50
Por lo tanto m <3

Step-by-step explanation:
Answer:
The length of the arc is 10 pi
Step-by-step explanation:
Mathematically, the length of an arc is calculated as;
theta/360 * 2 * pi * r
theta represents the central angle subtended by the arc which is a right angle according to the question (a right angle is 90 degrees)
r is the circle radius which is 20 inches
so we have the length of the arc as;
90/360 * 2 * pi * 20 = 40 pi/4 = 10 pi
Answer:
k=3/12
k=.25
Step-by-step explanation:
we need to get k by itself
because 12 is over k we need to get rid of it by moving it to the other side (multiplying) because it is 12/k we need to multiply it by 1/12
This eliminates 12 and leaves us with k=3/12
