Question

Need help with this, will be giving points

Answer 1

r=8.74

Explanation:

so firstly you need the formula volume equals to 1/3 S x h

you than multiply v9lume by 3

so 1920 equals to S x h

you devide 1920 by h so you get S=240

because S=πr2 you devide 240 by π

you get 76.433

that us r2 so you use square root and get 8.74 feet

Answer 2

• 8.74 ft

-----------------------------------------

Given a cone:

• V = 640 ft³,
• h = 8 ft

Find the radius.

Volume of cone:

• V = 1/3 πr²h

Substitute and solve for r:

• 640 = 1/3 × 3.14r²*8
• r² = 640*3/(3.14*8)
• r² = 76.433 (rounded)
• r = √76.433
• r = 8.74 ft (rounded)
