Answer:
184
Step-by-step explanation:
The prime numbers between 40 and 56 are 41, 43, 47, and 53.
Add the prime numbers.
41 + 43 + 47 + 53
= 184
In order to find this, you have to find both the top and the bottom volumes and add them together. To find the bottom volume you’d use the formula lwh or Length*width*height. First you’d substitute in the numbers for the formula and get 9yd*8yd*4yd and get 288yd cubed. Then to find the top one you use the same formula and use 4yd*3yd*2yd and get 24yd cubed. Finally you add the two volumes together and get 288yd cubed + 24yd cubed=312yd cubed
Answer:
a = 10 or a = -10
Step-by-step explanation:
a^-2 = 1/100
We know 100 = 10^2
a^-2 = 1/10^2
We know 1/b^c = b^-c
1/a^2 = 1/ 10^2
Multiply by a^2 on each side
a^2 *1/a^2 = 1/ 10^2 *a^2
1 = a^2/10^2
Multiply by 10^2 on each side
1 0^2= a^2/10^2 * 10^2
10^2 = a^2
Take the square root of each side
sqrt(10^2) = sqrt(a^2)
±10 =a
Step-by-step explanation:
The volume of a cylinder is given by :
r is the radius of the base of a cylinder
h is height of cylinder
The height of a cylinder is twice the radius of its base. It means that h = 2r
So, volume of cylinder becomes :
So, the volume of the cylinder is given by the expression .
