Surface Area (S.A.) is the area of all of the faces.
The base is square so its area is: side² = 8 cm x 8 cm = 64 cm²
The faces are triangles so the area of ONE face is: (1/2) x base x height =
(1/2)(8 cm)(14 cm) = 56 cm²

The sum of all of the faces are 64 cm² + 4(56 cm²) = 64 + 224 = 288 cm²

Answer: the surface area of the square pyramid is 288 cm²

Janet can do a job in 3 hours, and Garry can do the same job in 2 hours. If Janet works for 1 hour before Garry comes to help, h
lidiya [134]

Answer:

48 minutes

Step-by-step explanation:

Given that:

Time taken by Janet = 3 hours

Janet's rate = 1/3 job / hour

Time taken by Garry = 2 hours

Garry's rate = 1/2

Rate of working together :

1/3 + 1/2 = (2 + 3) /6 = 5/6 job/hour

If Janet works for one hour before Garry joins ;

1/3 of the job has been done by Janet

1 - 1/3 = 2/3 of the job left

Hence to finish the job together, it will take :

Fraction of JOB left ÷ rate of working together

(2/3 ÷ 5/6)

= 2 /3 * 6/5

= 12 / 15

= 4 / 5 hours

To minutes

(4/5) * 60

= 240/5

= 48 minutes

A cyliner has a radius of 16 m and a height of 24m. what is the approximate volume of this cylinder? (use �� = 3.14.)
vovikov84 [41]
<span>Cylinder Volume   =   </span><span>π <span>• r² • height
</span></span><span>Cylinder Volume   =   3.14 * 16^2 * 24
</span>Cylinder Volume   = <span> <span> <span> 19,292.</span></span></span>  cubic meters
My answer is much too big for those choices.

So, I'm guessing that 16 meters is the diameter.
If that's the case, radius = 8 meters and
Cylinder Volume   =   3.14 * 8^2 * 24
<span>Cylinder Volume   =   3.14 * 64 * 24
</span>Cylinder Volume   =   <span> <span> <span> 4,823.04 </span> </span> </span> cubic meters
So answer is "c"
