Answer:
Step-by-step explanation:
The lateral surface area is the product of half the circumference, and the slant height:
LA = πrh = π(11.4 cm)(23 cm) = 262.2π cm²
The total surface area adds the area of the base to that:
A = πr² +LA = π(11.4 cm)² +262.2π cm² = (129.96 +262.2)π cm²
A = 392.16π cm²
To find a percent from a decimal, you multiply the decimal by 100. So, the answer would be A.
Sec is 1/cos so sec -120 is 1/cos -120 which is -2
