Acone has a radius of 5 cm and a slant height of 10 cm. the area of the base of the cone is π cm2. the lateral area of the cone is π cm2. the surface area of the cone is π cm2.

base area: 25π cm^2

lateral area = 50π cm^2

surface area = 75π cm^2

Step-by-step explanation:

Put the given numbers into the appropriate formula and do the arithmetic.

The base area is the area of a circle, given by the formula ...

A = πr^2

A = π(5 cm)^2 = 25π cm^2

The lateral area is half the product of the circumference and the slant height. It is given by the formula ...

LA = (1/2)(2πrs) = πrs . . . . where s is the slant height

LA = π(5 cm)(10 cm) = 50π cm^2

The total surface area is the sum of the base area and the lateral area:

surface area = 25π cm^2 + 50π cm^2 = 75π cm^2

marco saved more.   he saved $35 more.

step-by-step explanation:

1+2+3+4+5+6+7+8+9+10 = 55

2*10 = 20

55-20 = 35
