The area of each triangular face is 40 square feet
<em><u>Solution:</u></em>
Given that,
Square pyramid has a base area of 64 square feet
The pyramid’s total surface area is 224 square feet
The total surface area of a regular pyramid is the sum of the areas of its lateral faces and its base
<em><u>Therefore, total surface area of square pyramid is given as,</u></em>
Total surface area = base area + 4(Area of traingular face)
Let "x" be the area of each traingular face

Thus area of each triangular face is 40 square feet
Answer:
Shayla is incorrect because if you add them it would be 8r+r2
Step-by-step explanation:
You should probably double check because the question it a little confusing and I could always be wrong.
Since both numbers are in the radical just multiply and get sq rt
25 times 4 =100
√100=10 answer
Answer:
2,3,6
Step-by-step explanation:
5,226 ...(1)
unit digit=6
6 is divisible by 2,
so (1) is divisible by 2.
last two digits=26 ,not divisible by 4,
so (1) is not divisible by 4.
5+2+2+6=15 divisible by 3 but not divisible by 9.
so (1) is divisible by 3 but not divisible by 9.
2×3=6,so (1) is divisible by 6.
unit digit=6≠0 or 5
so (1) is not divisible by 5 or 10.
Surface area of a sphere = 4πr²
Surface area of the sphere = 4π(0.8)² = 8.0 ft²
Volume of a sphere = 4/3 πr³
Volume of the sphere = 4/3 π(0.8)³ = 2.1 ft³
Answer: Surface area = 8.0 ft² and volume - 2.1 ft³ (Answer C)
