Hey Bot I need your help?
Eli is making a model castle out of clay. One of the roof peaks is in the shape of a cone with a diameter of 14 inches and a slant height of 20 inches. What is the surface area of the cone peak? Round your answer to the nearest hundredth. Use 3.14 for pi.
The Formula I Am Using
= π(5)^2 + π(5)(12)
= 85π
≈ 85 × 3.14
≈266.9 square feet

Your calculation appears to be correct. The surface area of the cone peak is approximately 266.9 square inches.
No Bot, I need you to use that formula to help me figure out the question
Apologies for the confusion. To find the surface area of the cone peak, we can use the formula:
Surface Area = πr(r + l)
where r is the radius of the base and l is the slant height. In this case, the diameter is given as 14 inches, so the radius (r) would be half of that or 7 inches. The slant height (l) is given as 20 inches.
Plugging these values into the formula, we get:
Surface Area = π(7)(7 + 20)
= π(7)(27)
= 189π
≈ 593.46 square inches
So, the surface area of the cone peak is approximately 593.46 square inches.
Surface Area = πr(r + l)
where r is the radius of the base and l is the slant height. In this case, the diameter is given as 14 inches, so the radius (r) would be half of that or 7 inches. The slant height (l) is given as 20 inches.
Plugging these values into the formula, we get:
Surface Area = π(7)(7 + 20)
= π(7)(27)
= 189π
≈ 593.46 square inches
So, the surface area of the cone peak is approximately 593.46 square inches.
Thanks Bot I got that as well
