Answer:
10
Step-by-step explanation:
If the sides of the rectangle is 6cm and 8cm, then we mean that, the length and breadth are 6cm and 8cm
The diagonal which cross at AX will be the hypotenus of the triangle formed by drawing the diagonal.
Hence,
Hypotenus = sqrt (opposite² + adjacent²)
AX = sqrt[(8²) + (6²)]
AX = sqrt(64 + 36)
AX = sqrt(100)
AX = 10
Answer:
B. Every 8 mins, 4 pics are taken
Step-by-step explanation:
x represents number of mins and y the number of pics taken per mins.
Hope this helps!
The correct question is
<span>The radius of a cylinder is 5" and the lateral area is 70pi sq. in. Find the length of the altitude.
</span>
we know that
[surface lateral area]=(2*pi*r)*height
height= [surface lateral area]/(2*pi*r)
surface lateral area=70*pi in²
r=5 in
so
height= [70*pi]/(2*pi*5)------> 7 in
the answer is
7 in
The main area formula is A= 5x s x r/ 2
where s is a side
r is the radius, r can be found as following
r is the hypothenuse, so tanα=a/S, where S=s/2=7
tanα=22/7=Pi, so <span>α=arctanPi= 72.3°
</span>for finding r, r = a/sin <span>α=22/sin 72.3°=23
</span>so finally
the area is A= (5x 14x 23 )/2=808
