Find the total surface area of this cone.
s2008m [1.1K]

The total surface area of the cone in terms of pi is 360π  square inches

Total surface area of a cone is expressed as

TSA =  πr(r+l)

Given that

radius = 10in

Height = 24in

Get the slant height 'l'

l² = h²+r²

l² = 24²+10²

l² = 576+100

l² = 676

l = 26in

Substitute the given values into the formula

TSA = pi(10)(10+26)

TSA = pi(36)(10)

TSA = 360π in²

Hence the total surface area of the cone in terms of pi is 360π square inches

during a special seasonal sale,a wholesaler allows retailers trade discount of 15% and 10% for prompt cash payment.Calculate the
d1i1m1o1n [39]

The cash price of the article is 88 cedis.

In this question, the article has a price, but paid in cash, there are two discounts.

  • Price of 115 cedis.
  • Discount of 15%, thus, 1 - 0.15 = 0.85 is paid, that is, the price is multiplied by 0.85.
  • Discount of 10%, thus 1 - 0.1 = 0.9 is paid, that is, the price is also multiplied by 0.9.

Thus, the cash price is:

P = 115\times0.85\times0.9 = 88

The cash price of the article is 88 cedis.
