Answer:
373.66 cm².
Step-by-step explanation:
The following data were obtained from the question:
Pi (π) = 3.14
Radius (r) = 7 cm
Slant height (l) = 10 cm
Surface Area (SA) =?
The surface area of the cone can be obtained by using the following formula:
SA = πr² + πrl
SA = (3.14 × 7²) + (3.14 × 7 × 10)
SA = (3.14 × 49) + 219.8
SA = 153.86 + 219.8
SA = 373.66 cm²
Therefore, the surface area of the cone is 373.66 cm².

Answer:
250 cm^3.
Step-by-step explanation:
Volume of the prism
= 12 * 5^2
= 300 cm^3.
Volume of the pyramid
= 1/3 * 25 * 6
= 50 cm^3
The volume of the space
= 300 - 50
250 cm^3.
C^2= a^2 + b^2 a=b
34^2= a^2 + a^2
1156=2a^2
a^2=1156/2
a^2=578
a=24.04
The side length is 24.04
Or I got this also
Using the special triangle theorem , an isosceles triangle has a diagonal equal to the square root of 2 of the legs of the triangle. In this case, the length of the legs is 34/ sqrt of 2 or equal to 24.04 units . This rule is based on the Pythagorean theorem
If the length of each side = x.
By Pythagoras' Theorem:
x² + x² = 34²
2x² = 34²
x² = 34² / 2
x² = 578
x = √578
