<span>A circular clock face has a diameter of 7 inches.
What is the area of the clock face?
Round to the nearest tenth.
A. 38.5 in.2</span>
Since we have a rectangle triangle, then we can find the other side of the triangle using the Pythagorean theorem.
We have then:

Then the surface area is given by the sum of the areas.
Triangle of the base and the top:

Rectangle 1:

Rectangle 2:

Rectangle 3:

Finally, the surface area is:

Substituting values:
Answer:
The surface area of a right triangle prism is:
B. 132
He pays $86.70 for the carpet. 8 time 10.2 equals 81.6.
10.2 divided by 2 equals 5.1. you will use 5.1 later.
81.6 + 5.1 = 86.7
There's about 22 because if you extend it by going 3+1 and so on it wont hit 90 exactly but it'll be 91, so 22 small sliced pizzas and 23 large sliced pizzas
The answer would be 46 - This is because you would do 85/10 to find the ratio. Then you would get 8.5. You would take 8.5 then divide 391 by 8.5 getting 46.
