Answer:

If it has a diameter of 10, divide it by 2 to get Radius (5) because Area = πr²

Then you do r * π *r which would be 78.5. so C is your answer.

The legs of an isosceles right triangle are 11 cm long. Find the length of the hypotenuse. Round to the nearest tenth if necessa
GaryK [48]
Its a squared + xb squared = c squared  so its 11 squared + 11 squared equals c squared. So I'm gonna take it down to the next step and say 11x11+ 11x11= c squared, then you end up with 121+121= c squared then you add those two and end up with 242= c squared, so then you find the square root of 242 so you should end up with 15.5 and the number goes on and on and on

The ice cream parlor serves spherical scoops of ice cream with a radius of 1 in. What is the approximate volume of 2 scoops of i
Varvara68 [4.7K]

Answer: 8.37 in³

Step-by-step explanation:

Given the following :

Shape of icre cream scoop = sphere

Radius (r) = 1 inch

Volume of a scoop of icecream = volume of sphere :

4/3πr³

(4/3) × 3.14 × 1³

1.333 × 3.14 × 1

= 4.1867 in³

Hence, the volume of 2 scoops of ice cream will be :

2 × ( volume of a scoop of ice cream)

(2 × 4.1867) in³

= 8.37 in³

I need some help
Firdavs [7]
<span>The best answer to this problem is 0.0823. np = 48 * 1/4 = 12 The exactly 15 would be written as 14.5 to 15.5. You then plug those into you equation separately. e1= (14.5-12)/3 = 0.833 and e2 =(15.5 - 12)/3 = 1.167) p(0.833<e<1.167)= 0.0808</span>
